Semiconductor heat-recovery Global wafer production before 2019 was 7 to 80% was booked

According to a report recently produced by the Department of Foreign Investment in the United States, it is pointed out that the current supply of global silicon sources is tight. China's Taiwanese wafer wafer manufacturing giant Global wafers, and 70% to 80% of production capacity by 2019 have been sold out.
The foreign investment report pointed out that the global wafer wafer production capacity of 12-inch wafers has increased by 20% since the first quarter of 2017. As for the 8-inch silicon wafers, prices have risen by more than 10% since the third quarter of 2017. In this regard, not only will global wafer management watch the rise of all sizes of silicon wafers likely to continue until 2019, but it also implies that 70% to 80% of production capacity by 2019 before customers have been ordered . dan202ut106
In fact, thanks to the continuous growth of semiconductor demand, coupled with the gradual opening of the capacity of Chinese fabs, the supply and demand of global silicon wafers have been seriously strained. Under such circumstances, Global Wafer's operating performance in 2017 was dazzling. Consolidated revenues reached NT$46,213 million, an increase of 150.8% from the previous year, and pre-tax net profit was RMB6.875 billion, which was also an increase of 411.3% from the previous year. The after-tax net profit attributable to the parent company was 5.275 billion yuan, an annual growth rate of 461.4%, and EPS per share was 12.68 yuan, a record high. lm2678t-adj
After the global wafer was separated from Sino-American crystals, it acquired the SunEdison semiconductor at the end of 2016 and became the world's third-largest semiconductor silicon wafer fab, second only to Japan's Shinho and Shenggao. Since 2017, the semiconductor silicon wafer market has ushered in a super-economy cycle, with tight supply and demand. Prices have been rising all the way, and it has also promoted global wafer operations. Recently, there were rumors in the market that due to the optimistic view of the future development of global wafers in the silicon wafer market, China’s “National Integrated Circuit Industry Investment Fund” (commonly known as the “Big Fund”), which specializes in investment in the semiconductor industry, will acquire the global wafer parent company Sino-US. Crystal to further control global wafer production capacity. However, such news was immediately denied by Sino-American crystal.
Although the news of mergers and acquisitions in the market was denied, it also saw the future development of global wafers. In particular, the semiconductor industry will continue to drive demand for silicon wafers. In addition to the current semiconductor silicon wafers, Global Wafer also invests in the production of new products, SiC and GaN, to meet the needs of customers for new product applications. Will boost sales revenue.

IDC: Tablet PC shipments worldwide dropped by 13 quarters

Market research firm IDC released data show that the global tablet PC market has 13 consecutive quarters of landslide. Some analysts said that the sharp decline in shipments of tablets are mainly due to the market is saturated, the product life cycle is long and alternative products increased.
Data show that in the fourth quarter of 2017, the global tablet shipments of 49.6 million units, down from the previous year's 53.8 million units 7.9%, the only good news is that the decline did not reach double digits, lower than in 2016. IDC calculated in the statistics of the traditional Tablet PC, as well as screen and keyboard separable variants. In the fourth quarter of 2017, Apple still occupies the market first, while Amazon surpassed Samsung for the first time in second place. The top five vendors have a market share of 69.6%, up from 61.3% in the same period of last year. bsm150gt120dn2
Apple's shipments were basically unchanged from the previous year. However, due to the poor performance of other tablets, Apple experienced another 2.3% increase in market share after two quarters of increase. Prior to this, the apple market share has dropped for 13 consecutive quarters. With a lower price iPad and an upgraded version of the iPad Pro, Apple maintained its market leadership.
In the fourth quarter of 2017, Amazon's tablet shipments increased by 2.5 million units, with a 6% increase in market share. The holiday season is usually the strongest quarter for the performance of Amazon, but this year's performance is particularly prominent, and the company surpassed Samsung in one fell swoop. IDC said it is due to Amazon offers a substantial discount, as well as the latest Amazon tablet integrated Alexa voice assistant. mg100q2ys42
Samsung's tablet shipments fell 1 million units year on year. IDC data shows that the proportion of detachable keyboards and screens in Samsung's tablet devices has increased, but such growth has not been able to make up for the decline of traditional tablets.
In addition, Huawei ranked fourth over Lenovo. Huawei's market share rose 1.2%, Lenovo fell 0.4%. Both companies shipped about 3 million units.
The rise of the Tablet PC is a coincidence, in the iOS and Android system victory over Saipan system, Apple released iPad running iOS, Andrews camp tablet products are rapidly mushroomed, 2011-2014 is the Tablet PC Rapid growth phase.
Among them, iPad in the tablet PC market has always maintained a dominant position, Android camp wins in the brand many, occupy the other half. In the battle between Android and iOS two camps intensified market, Windows 8 and 10 completed a perfect counter-attack, the three systems officially formed a strong situation.
Insiders pointed out that in the year 2017, the tablet PC market has shown such a trend, so the fourth quarter of the data is not surprising. In other words, the refreshment cycle of tablets is closer to that of traditional PCs, not smartphones, and this is the only category that has seen growth.
IDC analyst Jetsh Ublaney said: "So far, the keyboard and the screen can be detached deformation of the market thanks to the development of Microsoft and Apple in the United States product sales.However, this category can continue to be successful Depends on whether other PC makers are willing to join, more importantly, whether the user in other countries can accept this new type of product. "
However, from the current flat-panel market situation, manufacturers seem to have found a good way - specialization. Unlike the notebook market segmentation, Tablet PC specialization to be relatively simple. At present, Tablet PC products are divided into: adhere to the audio and video entertainment line; take the education line; take handwriting, painting, design line, support stylus.

For the Moore Law continued life: in the computer chip wiring by adding graphene

With the increasing size of the integrated circuit, the current fate of Moore's Law seems to be mostly focused on the improvement of silicon transistors. However, there are gradually researchers starting to start from other components: for example, connect the various transistors to form a complex circuit of copper. And graphene in which played a key role. lm3s9d90-iqc80-a1
In order to improve performance, integrated circuit density continues to increase, and in the same area of ​​the chip which plugged into more transistors, it means that more lines need to connect them. In 2000, the first group of copper interconnects was produced, with 1 km of copper per square centimeter; but today's 14 nm node processors were able to contain 10 km of copper in the same area.
Now the more sophisticated the chip, the copper wire becomes thinner, the resistance also increases, but has to carry more current to speed up the switching speed, improve performance, so will produce electromigration (Electromigration) phenomenon. The electrons of the copper wire will transfer the kinetic energy to the metal ions, so that the ions move toward the electric field in the opposite direction and gradually migrate, resulting in the diffusion and loss of the atoms of the copper wire, resulting in a short circuit.
The current solution is to set the copper wire in the trenches, and the inner walls of the trenches cover tantalum nitride with a thickness of 2 nm, which prevents the escape of copper. But this way top up to 10 nm and 7 nm nodes. As the process continues to shrink, the inner wall of 2 nm will become too thick. s50240
At the IEEE International Conference on Electronic Equipment, held in San Francisco last December, H.-S. Philip Wong from Stanford's electrical engineer and his team found that polystyrene was used to solve the problem of electromigration Phenomenon, and reduce the resistance. Wong said that although researchers have already studied other linings that may block electromigration, including ruthenium and magnesium, graphene can be thinner than any material. In addition, the semiconductor industry in fact try to avoid looking for new materials to spend too much time, but now the situation, if the copper life can no longer continue, you must use new materials (such as cobalt) to replace.
Stanford's team is currently working with Lam Research Corp. and Zhejiang University in China to test composite material routing to allow graphene to be produced online from copper. Corning has developed a special manufacturing method, will not damage the rest of the chip at the temperature (below 400 ℃), this coating of graphene composite material to suppress the effect of electromigration is the general copper 10 times , And only half the resistance.
Moore's Law to go on, in addition to the transistor, the potential is even the memory, lines and so have to join the ranks of improvement, and the role of graphene or will be more eaten.

Apple has not admitted iPhone6s battery problem

According to foreign media reports, if you are using the iPhone 6 or iPhone 6s, you may encounter battery problems. The most common situation is that even if the phone shows the battery still has enough power, but the iPhone6 ​​or iPhone 6s may still automatically shut down automatically.
Moreover, this is not a new problem, because the first time earlier this year, users have raised this issue. According to the "Forbes" reported that Apple official forums related information posted, a complaint about non-iPhone 6s models have TV problems post has more than 62 pages of replies, many of which users are said to be upgrading iOS10.2 After the problem, the problem is more obvious after the update, has seriously affected the normal use of the user. ff300r17ke3
Apple officials also launched a limited range of battery replacement items for the iPhone 6s and announced that the software upgrade will help other iPhone models to solve the battery problem. However, from the current situation, the effect of software upgrades seems very limited.
In this regard, "Fortune" magazine editor Jeff - John - Roberts (Jeff John Roberts) that the most annoying thing about this is that Apple refused to clarify where the problem in the end. Moreover, the company has been "pretending" other models do not exist similar problems, but only for some iPhone6s models start a limited range of battery replacement project.
It is reported that Roberts had their own iPhone 6 battery problems encountered, and "Fortune" magazine at least five employees of the iPhone 6 also encountered a similar problem. Roberts revealed that he learned that Apple retail store employees will provide users with an unusual solution, that Apple can re-install the firmware to the iPhone 6 in question, but this method may lead to the loss of important data, including short message content . cm1000ha-24h
Apple officially issued a formal statement to the Fortune magazine, although Apple in the statement written in a lot of text, but always evasive does not directly recognize the safety of its equipment battery, Apple's statement reads as follows:
We always work hard and are committed to providing the best products, user experience and customer support. We believe that this is the Apple user satisfaction in China and the world smartphone manufacturers have been the leading reason.
We have been very serious about customer complaints, including a limited number of iPhone abnormal shutdown. We also need to thank the media for conveying this issue to us. In the face of these problems, we will launch a formal investigation, and will carry out a detailed analysis of the involved equipment. When we find the problem, Apple will provide users with possible solutions.
Company survey found that in September 2015 and October during the production of a small amount of iPhone 6s used in the manufacturing process with too much outside air mixed with the battery parts. Two weeks ago, we launched a free replacement project for affected batteries around the world. Once again, we apologize for the inconvenience this has caused to users, but it must be noted that this is not a security issue.
At the same time, there are a small number of models not affected by the list of users also reflect their own equipment there is the problem of automatic shutdown, it is because some models will be in normal use for the purpose of protecting the device circuit components automatically shut down. To gather more information on this issue, we will have an additional diagnostic feature built into the iOS software update expected next week. By collecting this information, we can improve the algorithm used to manage battery performance and shutdown. And if this improvement proved to be feasible, we will be added to the future of the software update push.

KIT researches multi-core processors for automotive and industrial applications

Safety-critical applications in automotive, aviation and industry 4.0 will require a significant increase in digital computing performance. This can be provided via Multicore technologies. The ARAMiS II project, developed at the KIT, aims to increase safety, efficiency and comfort by using multicore technologies in vehicles, aircraft and production facilities.
The demand for digital computing performance is increasing enormously, among other things by highly automated vehicles and real-time networked machines, but also by the increasing integration and interaction with other products and services. The use of Multicore technologies significantly increases the computing power of embedded systems in vehicles, aircraft or industrial plants. Multicore processors have multiple processor cores that must work in parallel. This can increase the computing power enormously, but the development is more complex for several processor cores - for example, when it comes to timing or critical point critical requirements. 7101j52zqe22
Multicore processors are now used successfully in many applications, such as PCs, tablets and smartphones. However, safety-critical applications in mobility and industry require additional complex requirements, which is why multi-core systems have hardly become established in industrial embedded applications or in the automotive industry. The requirements for strict safety certifications have so far hardly been met by these building blocks .
"In the new ARAMiS II project, we are creating the indispensable methodological prerequisites to increase safety, efficiency and comfort in the use of multicore technologies and make them industrially available. The results of ARAMiS II are supplemented by standardization activities of the domains concerned and are thus made available to other industry partners. "Says Professor Jürgen Becker, spokesman of the institute management of the Institute for Information Technology (ITIV) of the KIT and together with Falco Bapp of the ITIV coordinator of ARAMiS II. 7201k2zge
In its predecessor, the ARAMiS project, KIT has successfully demonstrated with numerous partners from research and industry that multicore technologies can be used and integrated in safety-critical applications. Based on this, ARAMiS II is to develop, develop and optimize the efficient development processes, especially the systematic tool chain and the industrial platforms with the necessary methods, for the reliable use of multicore architectures. Demonstrators in the domains of automotive engineering, aerospace and industrial automation should demonstrate the applicability of the developed concepts and methods across all domains.
In a kick-off meeting on 1 and 2 December 2016, all partners identified the next activities in the six subprojects: applications and requirements, structured multicore development, multicore methods and tools, multicore platforms, and architectural patterns , Implementation and evaluation, results assurance and utilization.
The consortium of ARAMiS II consists of 33 partners. In addition to renowned research facilities, leading manufacturers from the automotive and aerospace industries as well as the industrial sector as well as various suppliers, software and tool manufacturers are participating. Continental, for example, is an industry spokesman in ARAMiS II, Audi, Bosch, Airbus and Siemens.
Like its predecessor, ARAMiS II has been designed for three years; The project volume totals more than 26 million euros. ARAMiS II is funded by the Federal Ministry of Education and Research (BMBF) with around 15 million euros.
