Today, semiconductor ring toughest thing in the Moore’s Law is about to end, the researchers had to find a replacement for silicon semiconductor material to improve performance, and the carbon nanotubes are considered to be the most likely one to replace silicon material.

Recently, the University of Wisconsin-Madison has been made in the development of this material by leaps and bounds breakthrough, school materials scientists successfully developed 1-inch carbon nanotube transistors, and for the first time while in the performance of silicon transistors and beyond gallium arsenide transistors.

As the name suggests, carbon nano-channel transistor is composed of carbon nanotubes as a conductive material made of transistors, which wall only one atom thick, this material is not only conductive properties, and the volume can do than it is now 100 times less silicon transistors . In addition, the carbon nanotube transistors ultra-small space makes it possible to quickly change the direction of current flowing through it, so they can reach 5 1/5 times the speed or power consumption of only silicon transistors silicon transistors.

However, because of technical bottlenecks in the past for a long time researchers have not been able to develop a better performance than silicon transistors and gallium arsenide transistors of carbon nanotube transistors, not to expect their applications in various types of electronic equipment.mds690

It is understood that, in accordance with traditional practice, usually carbon nanotube hybrid metallic nanotubes, but these metallic nanotubes can cause a short circuit the electronic device, thereby undermining the conductive properties of carbon nanotubes. University of Wisconsin-Madison researchers this another way, they use a polymer replace almost all of the metallic nanotubes, the content of metallic nanotubes down to 0.01% or less, this approach greatly enhance the conductivity.

In addition, the team also made to improve the process, they developed a successful method to remove the residue dissolved carbon nanotube production process produces.

Materials engineering professor at the University of Wisconsin-Madison Mike Arnold, said: “Our research while overcoming multiple barriers faced by carbon nanotubes, eventually won the first super-performance silicon transistor 1-inch carbon nanotube transistors many ideas Carbon. still to be achieved, but we finally realized after two decades to catch up. “adsp-21020kg-100

So the question is, graphene and carbon nanotubes who will become the next generation of semiconductor materials?

2009 AMD to own wafer manufacturing business spun off Middle East oil sold Tyrant fund established GlobalFoundries Inc. (GF), although AMD has holdings of shares of GF company, and over the years GF stumbling process, but they have been AMD OEM partners are important, but fortunately finally stabilize the 14nm node down for AMD OEM Polaris and Zen processor. Recently AMD and GF has signed a $ 335 million partnership agreement, AMD before the end of 2020 will continue to buy GF wafer, the two sides will promote cooperation 7nm process development.

Signed between AMD and GF is the WSA (Wafer Supply Agreement) wafer supply agreement period up to five years, the last time the agreement was signed in 2011, and it was not the GF 32nm process immaturity, AMD is no longer used to purchase wafers fixed price and switch to cut out the cores can be used to pay. The agreement signed calculated from January 1, 2016, as of December 31, 2020, the year in which the wafer price is fixed, the next four years to determine the price of the frame.

Under the agreement, the two sides in addition to up to five years of wafer supplier cooperation, the will to work together to promote 7nm process development –GlobalFoundries has confirmed that canceled the 10nm process, AMD did not mention 10nm chip planned, both from 14nm directly kill the future 7nm process.

But it can not be completely ruled out AMD, there are other plans, because in the agreement AMD also retains the possibility of using other fab manufacture of certain products. Although this is only the possibility of agreement on the increase but this provision means that AMD may choose other foundries – on 14nm process is, GlobalFoundries now capacity can not fully meet the needs of AMD.

Agreement the two sides signed a total value of up to $ 335 million, of which $ 100 million in cash installments, starting from 2016 Q4 2017 Q3 quarter until quarter.

From Massachusetts Amherst microbiology research team has found a new method, it is possible to create a fine human hair than 6,000 times the biological wire, it is called “microbial nanowires.”

The researchers said that this microbial nanowires by a soil bacterium genetically modified after – sulfur-reducing bacteria to stick made of their diameter of 1.5 nm, a human hair is about one in 6000, but increased conductivity 2000 times and is very durable.

Principal investigator of the research team of Dr. Derek R. Lovley said microbial nanowires that can be mass-produced, because they are made of cheap materials, such as amino acids can be obtained by fermentation of bacteria.

Dr. Derek R. Lovley in an interview said: “We have the possibility for synthetic biology wires are very excited, they can be applied to electronic products and even new flexible solar devices.”

It is understood that the study was funded by the Office of Naval Research, and therefore microbial nanowires could also be used in the military field. For example, nanowires may supply current to the microorganisms, and the like to produce a gasoline fuel – butanol. In addition, the nanowires can also provide some microbes current, and collect contaminants, toxins or explosives signal.

For ordinary consumers, the main purpose of the microbial nanowires can be applied to the smart phone, so the small size of the phone is able to have more memory space.

Things related to the current market has favored topic. According to forecasts, by 2020 the world will have more than 100 billion networked devices. It is noteworthy that these devices will be more than half the power consumption is very sensitive. MCU Therefore, low power consumption, high performance, especially in integrated wireless communication solutions will be taken seriously. It’s more than a simplified design that allows designers to more downstream networking equipment market.

Things attention to the average power consumption

With the increase of people and things, things and things connected to the next era will be one hundred billion connections, in addition to actively promote the development of ISO work on technical standards, market prospects for low-power M2M business is very broad. In this regard, Oivind Loe Silicon Labs 32-bit microcontroller product marketing senior manager in an interview, said: “Energy efficiency is a critical component in the application of things some of the characteristics of networking applications, such as meter reading and smart. smart credit card, there may be even ultra-low power requirements; in order to fit a variety of applications, MCU must have a well-designed energy mode, supports MCU current consumption to achieve a balance between functions and response time. ”

Microchip’s appliance unit IoT solutions marketing manager Xavier Bignalet also pointed out: “Today, connectivity applications power consumption is a necessary condition, even in some applications, the battery life of 20 years sustainable.”

But it is worth noting that networking applications for low-power chip demand is not all as low as possible under different scenarios and have unique needs. Deputy Minister of Renesas common Solution Center Integrated Marketing Wang Feng in an interview said: “If things specific to the application, it is often difficult to distinguish clearly standby power consumption and run things because the device, the device most. the case is in standby and between work, or a high frequency conversion between the two, the average power consumption becomes important. ”

In view of this situation, many semiconductor companies for the development of low-power MCU networking chips invested a lot of efforts. “Renesas 16-bit and 32-bit Rx series L78 series has a low-power features. Renesas many products using a proprietary kernel, have more space to optimize power consumption of the time. In addition, Renesas has its own chip peripheral products, with its own production facilities, joint action in the core, peripherals and technology in three aspects, the product can achieve low power consumption. “Wang Feng said.

Oivind Loe said: “MCU designed energy mode, balanced current consumption and response time and features an optimized trade-off between this method enables to provide MCU current consumption, performance, size and cost of the right for many applications. combination.”

Improved design architecture is an important way of saving

Specifically, MCU power consumption levels include static power consumption to run in two parts. Consider the actual application, the static power consumption of the chip in a sleep state or non-operating power, and dynamic power that is consumed by the MCU running power. The final performance of the system is to calculate the average power consumption. They have a level of power consumption and manufacturing processes are a great relationship, what kind of process, the product determines the static power consumption and operating advantages and disadvantages.

In addition, some vendors from the entire infrastructure improvements, low-power networking environment. NXP Semiconductors Greater MICR microcontroller Jin Yujie director of product marketing, said: “NXP introduced unique asynchronous MCU structure, MCU, respectively, in one integrated ARM Cortex A7 and Cortex M4 core, usually can be maintained with M4 core operation, especially in the standby mode of operation, maintaining low power consumption. ”

Renesas another way to take, but also a better solution to this problem. “The demand for features introduced in Renesas MCU in Snooze mode, you can do the standby MCU core, peripherals work. That is when you use Snooze mode, the peripherals will judge outside instruction comes, the need for core work, only confirm this demand later will really wake kernel, so that the efficiency of the system has increased significantly. “Wang Feng said.

Reduce peripheral power consumption, but also reduce the power consumption of the chip as a whole effective way. According to Jin Yujie introduction, NXP products by API software when MCU, MPU complete the task, some interfaces do not turn off to save power.

Microchip also peripherals mining potential. “Microchip’s 8-bit microcontroller with a part independent of the core peripherals can well achieve low power requirements, only a little or no CPU intervention, further reducing power requirements. In addition, such as LCD, op amp, RTCC , touch sensing, USB, DMA and encryption engines, low-power peripherals to enhance the performance of the MCU to a new level, to minimize system-level power. “Xavier Bignalet said.

Challenges to deal with fragmentation

Things biggest feature is the fragmentation, how to make MCU chip to adapt to the application of things, but also a challenge. “Things is not just a single market, but encompasses all areas of vertical markets Thus, for networking equipment is not a common specification: wearable devices with stringent power consumption requirements; and heavy industrial equipment. not demanding low power consumption can be the current situation is that most chip makers in order to balance the cost of using a common MCU to try to cover most applications. “Xavier Bignalet said.

However, this situation is improved. “With the evolution and development of networking applications markets semiconductor technology, in the future there may be makers of things for the market to develop a dedicated chip, commonly used in existing MCU analog peripheral functions may be removed, so as to focus on algorithms and connectivity, lower power consumption and cost at more advanced semiconductor process. in simple terms, is to control the main functions of the MCU and intelligently analyze / connection as the main function of the chip may things separation but co-exist. “ARM China embedded applications market manager Geng Lifeng representation.

Occasion of the active OLED (AMOLED) panel global shortage, analysts pointed out that Samsung’s technology leadership AMOLED panel of at least three years, as well as production, yield advantages, the threshold is high AMOLED, Samsung Patent mines, also had to raise attention.

IHS Research Director Technology represents Yang Jingping, AMOLED is mainly used in small and medium-size panels, the current application to smart phones, smart watches based, future expansion and automotive panels. However, the threshold is high AMOLED, there are a lot of know how (key technology), technical complexity than the TFT-LCD is difficult to many, AMOLED recipe must keep trying.

Yang Jingping said: “The small and medium size AMOLED supply accounted for more than the highest Samsung, declared to give up the seventh-generation TFT-LCD panel makers, panel currently in short supply, the price of 40-inch successive occasion, Samsung seems to suffer, but this is a short space long and more, after all, the traditional LCD panel after the mainland to join the competition is fierce. ”

She stressed that Samsung’s AMOLED technology leader at least three years, as well as mass production, yield, patents and capital, as a barrier to enter the AMOLED.

Analyst Fang Mu Ru also believes that Apple’s new iPhone mobile phone plan to use AMOLED panels, will enable mobile phone operators to switch to AMOLED panel, setting off small and medium-size LCD panels for another war. Taiwanese companies to enter the AMOLED panel, should pay attention to Samsung’s patent mines.

Large-size AMOLED places LG fastest growing applications on the 55-inch OLED TV, but Fang Mu Ru believe, OLED TV in color saturation although high, but the price is high, frequently nearly 20 million price, and 4K2K LED TV prices have a big gap, to spread yet to be priced close to the people.

The graphics pioneer Silicon Graphics (SGI) is part of the IT giant Hewlett Packard Enterprise. SGI is today best known for high-performance computing solutions and to strengthen HP especially in data analysis.

SGI was by entrepreneur Jim Clark lifted in 1981 (later Netscape co-founder) from the baptism and initially specialized in Unix-based graphics workstations, which were due to their efficiency, inter alia at scientists and computer graphic extraordinarily popular. A big PR coup succeeded SGI in 1993, when Steven Spielberg’s Jurassic Park Dino shocker came in the cinemas.

In its day, pioneering computer-generated special effects were mostly built on Silicon Graphics workstations. In addition, SGI had bought the Canadian software company Alias, which had developed in the eighties the most powerful graphics and animation software, which was used for Terminator 2 and Jurassic Park.

These once dominant position crumbled but increasingly as powerful graphics hardware was also increasingly available for cheaper PCs. 2004 had to sell its SGI graphics software arm. Silicon Graphics therefore tried to reposition itself as a supercomputer specialist, which failed. Meanwhile Silicon Graphics had even the supercomputer manufacturer Cray adopted but rejected again after four years.

The company had to apply for 2006 and 2009 for creditor protection under Cahpter 11th Shortly after the second bankruptcy SGI was acquired by Rackable Systems, a specialist in server and storage solutions. Rackable notified thereupon into SGI.

In recent years, Silicon Graphics then dealt with big data solutions. The HP Enterprise Manager Antonio Neri told the Wall Street Journal, SGI dispose on systems with extremely high storage capacity, which made it possible to operate large databases. This was crucial for the acquisition.
