Due to the weak smartphone market and rising uncertainty in the cryptocurrency mining market, coupled with the appreciation of the exchange rate of the Taiwan dollar against the US dollar, TSMC estimated that the consolidated revenue in NT in the second quarter will be between 2,277.6 and 230.68 billion yuan. During the period, it fell by 7.0 to 8.2% from the previous quarter, which was lower than market expectations. TSMC also reduced its annual revenue growth target from 10-15% estimated at the beginning of the year to 10%.
Affected by the negative impact of TSMC's downward revision this year, US stocks earlier in the day, TSMC ADR fell by more than 6%, fell to 39.38 US dollars.
Foundry leader TSMC held a legal briefing yesterday (19th). The company’s consolidated revenue in the first quarter reached US$8.459 billion, a decrease of 8.2% from the fourth quarter of last year and a 12.7% increase from the same period of last year. Affected by the appreciation of the exchange rate against the United States dollar, the NT$ consolidated revenue for the first quarter of the year fell 10.6% to 248.079 billion yuan, still 6.1% higher than the same period last year.

TSMC’s co-chief executive Wei Zhejia said that the main reason for the outlook adjustment is that the demand for smart phones is lower than expected, and the demand for cryptocurrency mining ASIC market is also full of uncertainties.
TSMC's average gross profit margin in the first quarter was 50.3%, and its operating profit rate was 39.0%. It was in line with its previous performance outlook. The single-season parent company's net profit after tax fell 9.6% to RMB 89.788 billion, a growth of 24.6% compared to the same period last year, and net profit per share. 3.46 yuan, in line with market expectations. TSMC said that 28nm and more advanced process revenue has reached 61% of the total wafer sales.
However, TSMC’s outlook for the second quarter was conservative, mainly due to the weak demand from the smart phone market. It is expected that the consolidated revenue will be between US$7.8 billion and US$7.9 billion, representing a decline of 6.6 to 7.8% from the previous quarter and 10.5% from the same period of last year. ~11.9%. Under the assumption that the exchange rate of the New Taiwan dollar against the US dollar is 29.2 yuan, the consolidated revenue in NT will be between 2,277.6 and 230.68 billion yuan, down by 7.0 to 8.2% from the previous quarter, which is lower than market expectations, but the same period of last year. Compared to still grow 6.5 to 7.9%. BTW58-1500R
TSMC estimates that the gross profit margin for the second quarter is between 47 and 49%, and the operating profit rate is between 35 and 37%. This compares with the first quarter and the same period of last year. TSMC said that the main reasons include the appreciation of the Taiwan dollar and poor product mix.
Regarding cryptocurrency computing market ASIC market changes, TSMC said that related performance in the second quarter is still better than the first quarter, and the second half will be better than the first half, but after the recent cryptocurrency price drop, 28nm ASIC demand turns Weak, strong demand for 20nm and more advanced process ASICs, so this market is still conservative and cautious.
TSMC also revised its outlook for the semiconductor and foundry market this year. TSMC estimates that the annual growth rate of the semiconductor market that does not include memory this year is about 5%, which is only 5-7 percent of the bottom margin estimated at the beginning of the year; the foundry market grew by 8% from last year, slightly lower than the forecast at the beginning of the year. Increase by 9 to 10% annually. TSMC’s revenue in US dollars this year is about 10% higher than last year, lower than the annual increase of 10% to 15% expected at the beginning of the year.

According to the official website of the Ministry of Science and Technology, a few days ago, MIT engineers designed an artificial synapse that can precisely control the intensity of current flowing through it, similar to the way that ions flow between neurons, and has used silicon germanium. Made of artificial synapse chips. The chip and its synapses can be used to identify handwritten samples in simulation studies with an accuracy of up to 95%. The research results were published in the journal Nature-Materials, marking an important step for portable, low-power neuromorphic chips. BSM50GX120DN2
It is reported that there are about 100 billion neurons in human brains. Neurons pass instructions through 100 trillion synapses, enabling the brain to recognize patterns with lightning speed, complete memories and perform other learning tasks. Researchers in the emerging field of "neuromorphic computing" have tried to design a computer chip that works like a human brain and works by simulating signals similar to neurons. In this way, small neuromorphic chips can handle millions of parallel computations as efficiently as the brain, and only large supercomputers are currently possible. The problem that needs to be solved in this portable artificial intelligence method is synapses.
The researchers used silicon germanium to make neuromorphic chips consisting of artificial synapses, each consisting of "input/hide/output neurons," each neuron connected to other "neurons" through filament-based artificial synapses. . Each synapse is about 25 nm, and the difference in ion flow between them is only 4%, which is the most consistent device that can be achieved in the laboratory and the key to demonstrating artificial neural networks. The researchers then performed computer simulations of the artificial neural network to identify handwritten samples. The accuracy rate reached 95%, while the accuracy of the existing software algorithms was 97%. FS450R12KE3
The team is making simulation-based neuromorphic chips that can be used to identify handwriting tasks, and expects to use its artificial synapse design to create more compact, portable neural network devices for performing complex calculations, eventually replacing fingertip-sized chips. supercomputer.

In the global technology industry, one indicator of the technical strength of each company is the number of patents. According to the latest news from foreign media, the latest statistics show that as of the end of last year, the cumulative number of patents registered by Samsung Electronics in the United States exceeded IBM's number one for the first time, and the organization also pointed out that IBM's technology research and development is moving toward aging.
Almost all technology companies in the world have registered patents in the United States, so the number of patents acquired in the United States has also become an authoritative comparative indicator. fz1200r12kf5
According to the Yonhap quoted from IAM and other organizations on Sunday, Samsung Electronics has accumulated 75,596 patents in the United States as of January 1, equivalent to 1.6 times that of IBM.
IBM holds a total of 46,643 patents, and it has been the largest patent-owned company in the United States for the past 25 years.
The above statistical report points out that Samsung Electronics not only surpassed IBM’s number of patents, but that in the foreseeable future, the company may always occupy the top spot. cm75ye13-12f
The report pointed out that although IBM used to lead in the number of patents, some of its patent assets are aging. In addition, IBM will give up some patents at an early stage. "As patent assets age, IBM must further intensify innovation, or It is the acquisition of patent assets to adapt to rivals' competition."
Japan's Canon, which traditionally manufactures digital cameras, holds 38,996 patents in the United States, ranking third. With the gradual replacement of digital cameras with smart phones, Canon has begun a large-scale business transformation, targeting medical devices and other fields. A large number of patent libraries will also promote Canon's transformation strategy.
Microsoft Corp. has 33,327 patents, ranking fourth, and Intel Corp. is ranked fifth, acquiring 30,985 patents.
Another Korean company, LG Electronics, ranked seventh and held a total of 28,223 patents in the United States.
Among the top 100 companies, US companies accounted for 46 seats, and European companies took up 14 seats. China's Huawei Corporation ranked 61 and Lenovo Group had 93.
Huawei and Lenovo are also the most internationalized technology companies in China. Huawei has sold telecommunications equipment and smart phones globally. Last year, Ericsson exceeded Ericsson as the world’s largest telecommunications equipment supplier. Lenovo Group is the second largest personal computer manufacturer in the world.
Among other Korean companies, SK Group ranked 56 in the United States, LG Display ranked 65, and Korea Electronic Telecommunications Research Institute ranked 82.
Samsung Electronics overtook IBM to become the largest number of US patents, but it was not unexpected. IBM used to be the overlord of the personal computer era, but later it sold its computer business and focused on corporate IT consulting, high-performance servers, and large computers. In the Internet era, IBM's industry status began to decline. The company has entered the emerging cloud computing market, but its competitive strength is far inferior to that of Amazon.com.
Samsung Electronics is the world’s largest consumer electronics company. It owns a wide range of products and raw material components such as display panels, memory chips, and semiconductors. Samsung is also the world’s largest smartphone manufacturer. Samsung’s mobile phones are often able to rely on excellent R&D capabilities. Launched major innovations including curved screens.
In addition to traditional household appliances, raw materials, mobile phones and other services, Samsung Electronics also follows the trend and has laid out various emerging technologies such as voice assistants, artificial intelligence, machine learning, automatic driving, virtual reality, and augmented reality. Technological R&D in these areas naturally promotes the continued growth of Samsung Electronics' patents.

Reuters reported on March 28th, Beijing time, as the world's third-largest smart phone manufacturer, Huawei launched its new flagship product, the P20 series, in Paris on Tuesday in order to seek new products in the European market. breakthrough.
In the current European smart machine market, competitors Samsung and Apple have made great progress. However, Huawei's P20 series, with its rich camera capabilities and aggressive pricing strategy, is trying to compete positively with the Samsung Galaxy S9 and Apple iPhone X in the highly homogenized high-end smartphone market. bc556ap
Huawei said that the high-profile version of the P20, the P20 Pro, is equipped with three cameras and sensors, which also makes the image clarity of this product the leader in existing smartphones. Samsung’s flagship product, the Galaxy S9, launched in Barcelona last month upgraded the camera, and the Huawei P20 Pro is a clear response to Samsung’s product.
At the press conference in Paris, Huawei said that the basic P20 is priced at 649 euros (about 5053 yuan), while the high-priced P20 is priced at 899 euros (about 7,000 yuan). In contrast, according to Samsung's website data, the price of the Galaxy S9 and the high-priced version of the Galaxy S9+ is about 739 euros (about 5754 yuan) and 869 euros (about 6,676 yuan) respectively.
The European market will be the key for Huawei to become the world’s second-largest mobile phone manufacturer. In China's domestic market, Huawei is facing fierce competition from domestic rivals, but the European market is different. Thomas Husson, an analyst for consumer equipment at Forrester, a market research organization, said: “Given its absence from the US market, Huawei’s challenge in the European market is how to enhance its brand personality and gain more market share.” s1227-66bq
Huawei stated that in the first half of 2017, the company’s shipment volume in the European market increased by more than 50%. According to data provided by market research company Counterpoint, in the two major mobile phone markets in Europe—the Italian and Spanish mobile phone markets, the current Huawei mobile phone shipment share has exceeded that of Apple and Samsung. Counterpoint estimates that in recent years, the share of Huawei mobile phones in Western Europe has risen to 12%.
The share of Huawei smartphones in the UK and France accounted for 5% and 6%, respectively, and it was lower in the European market. In these countries, Huawei is strengthening its business.
However, Counterpoint analyst Peter Richardson said that Huawei has begun to face greater competition in the European market due to the recovery of Nokia mobile phones developed by HMD Global and its competitors from China. Xiaomi is increasingly powerful in this market.
The increase in the share of Huawei smartphones in the European market will help the company to make up for the disadvantages it has encountered in the US market. The chairman of the U.S. Federal Communications Commission (FTC) said last week that for Huawei, the FTC plans to adopt "active measures" to ensure the integrity of the US communications industry supply chain.

South Korean technology giant Samsung officially announced on the official website on the official website of a new generation of mid-range mobile processors - Exynos 9610. The processor is affiliated with the Exynos 7 series of Samsung mobile processors. The biggest feature is the addition of visual depth processing, which can achieve 480fps slow-motion photography at 1080p resolution, or 4K 120fps recording and playback capabilities. Samsung pointed out that Exynos 9610 will adopt Samsung's new generation of 10-nanometer LPP process technology. On the processor side, the 8-core architecture is still based on the classic size core 2.3GHz A73×4 plus 1.6GHz A53×4. Under the DynamIQ big.LITTLE architecture, task scheduling tasks can make full use of each core performance of the CPU, regardless of whether it is a large or small core. It is also equipped with an embedded Cortex-M4F coprocessor to handle the daily sensor message processing. On the GPU, although the public version of the G72 architecture has greatly improved the GPU performance, the Exynos 9610 adopts the Mali-G72 MP3 with only three cores. The future may not be sufficient. bc556ap
For baseband chips, the baseband chip used by the Exynos 9610 supports up to LTE Cat.12 3CA 600Mbps downlink speeds, and up to Cat.13 2CA 150Mbps uplinks. The wireless connection function supports 802.11 ac 2×2 MIMO Wi-Fi and Bluetooth 5 and FM functions, and satellite positioning supports the mainstream GPS, Beidou, Galileo, and GLONASS systems.
Finally, because Samsung knows that photographing and photography have become the most frequently used features of consumer mobile phones, the Exynos 9610 has specifically added a visual depth processing module to enable deeper facial detection, multi-frame noise reduction, and simulated depth of field. Other functions. At the same time, the CPU supports 480fps slow-motion photography at 1080p resolution, or 4K 120fps recording and playback. These features make the future of the phone with the Exynos 9610 have a good photography function. Currently Exynos 9610 is ready for mass production. Samsung said Exynos 9610 will begin large-scale commercial use in the second half of 2018. s1227-66bq

Later this year, hardware-level protection will be applied to data centers and PC products.
In order to address the vulnerability discovered by the Google Project Zero team earlier this year, Intel and the technology industry faced a major challenge. Thousands of colleagues throughout the industry have made unremitting efforts to ensure that we are able to deliver on our common primary commitment: to protect customers and their data. With humility, I am sincerely grateful to the people and colleagues around the world for their commitment and hard work. And I'm convinced that when companies need help urgently, companies, even competitors, will work together to cope. xc18v04vq44i
However, there is still a lot of work to do. As the security situation continues to evolve, we know that there will always be new threats. This prompted me to draft a pledge to “safeguard safety first” in January. Intel has always been very concerned about security, and now, more than ever, we are sticking to the principles I have stated in these commitments: customer-first urgency, transparent and timely communication, and ongoing security.
Today, I would like to provide some updates to illustrate our continued progress in fulfilling these commitments. First of all, we have now released microcode updates for all Intel products released in the past five years in order to protect against the vulnerabilities discovered by Google through the side channel approach. Secondly, I would like to express my appreciation to all industry partners and express my gratitude. They work closely with us to develop and test these updates, and to ensure that these updates have been productized. AT24C16BN-SH-B
These updates are now in place and I encourage everyone to ensure that their systems are always up-to-date. This is one of the simplest ways to achieve lasting protection. I would also like to take this opportunity to share more details about our future defense of these vulnerabilities at the hardware level. This is also my commitment at Intel’s recent earnings conference call.
Vulnerability variant 1 will continue to be addressed through software defenses, and we are currently working on changing the hardware design to further address the other two vulnerabilities. We have redesigned some of the components of the processor to introduce a new level of protection through partitioning, which will prevent both variant 2 and variant 3 of the vulnerability. You can think of this partition as an extra "protection wall" between the application and the user's privilege level, setting a barrier for intruders.
These changes will be the first to be applied to our next-generation Xeon Extensible Processors (codenamed Cascade Lake) and 8th generation Intel Core processors expected to ship in the second half of 2018. When these new products come out, the key is to ensure that they provide people with the desired performance improvement. Our goal is not only to provide the best performance, but also to provide the safest performance.
However, our work is not yet over. This is not a one-time event but a long-term commitment. We attach great importance to this. Customer first urgency, transparent and timely communication, and continuous security. This is our commitment, my commitment to all Intel employees.

Professor Ren Tianring, a professor of microelectronics at Tsinghua University, published an article titled "High Sensitivity and Wide Linear Range Graphene Pressure Sensor with Bionic Randomly Distributed Structure" at ACS Nano, Sensor with Random Distributed Spinosum for High Sensitivity and Large Linearity. The similar biomimetic structures are proposed based on human skin-sensing microstructures. The combination of microstructure and distribution mode solves the contradiction between sensitivity and linear range. The comprehensive improvement of device performance provides a new idea. dan202ut106
In recent years, the flexible force micro-nano sensor has become a research hot spot in the field of human physiological information monitoring and detection in particular, and a large number of related industry companies have been established one after another. Compared with the traditional silicon-based devices, due to its comfort, fit and wearability and other aspects of the characteristics of the widely used in physical and chemical monitoring of the human body, but as a mechanical device, two important indicators of sensitivity and linearity The contradiction between has not been well resolved. The devices that are usually prepared need to sacrifice one index to serve the other one, which often limits the scope of its practical application. Solving the contradiction becomes a difficult problem.
Based on the highly sensitive response of human skin, especially the fingertips to different sizes of stresses, Ninteen's group proposed the preparation of a similar structure based on the study of its microstructure. The sandpaper was used as a template to form a flexible substrate. The graphene was used as a mechanosensitive layer after being reduced at high temperature to prepare a pressure sensor with acupuncture morphology and random distribution. The sensor exhibits excellent stability, fast response and low detection limits, enabling high sensitivity over a wider linear measurement range. Among them, the acupunctural changes in the contact area mainly contribute to the high sensitivity, and the random distribution mainly contributes to the wide linear range. The combination of the two largely resolves this contradiction. lm2678t-adj
Due to the high sensitivity and wide linear range of the sensor, the research group successfully applied to the monitoring of various physiological activities of the human body, such as pulse, respiration and voice recognition, as well as the monitoring of walking posture such as walking, running and jumping, As well as walking gait monitoring. The use of wearable high-performance mechanical sensors to acquire various physical activity parameters of the human body will have important practical significance in terms of personal health and medical treatment, and has great application prospects.
The research results have been supported by the National Natural Science Foundation of China and Ministry of Science and Technology projects.
