The design engineers of US Silicon Valley have always believed that FD-SOI technology is a bit like "wolf." The boy in the story is always seemingly coming, but it has not been achieved - at least not in Silicon Valley.
Compared to the traditional block CMOS technology, the traditional block CMOS technology that Intel is continuously used in each process node, the FD-SOI process is "new stuff" to most American design engineers, and it is "shipping", but The FD-SOI's ecosystem has not been formed, but also the main reason opponents regardless of the technology, they never want to gamble.
Despite this, FD-SOI has supporters including NXP Semiconductors, SSP Semiconductors, STMicroelectronics; this year, NXP revealed that the FD-SOI technology will be fully adopted, and will be with its lowest work The general purpose application processor I.MX 7ULP is the starting point.
At the same time, FD-SOI has many new developments in the Asian market, of which globalfoundries, the wafer, industry, is the fastest running; the FD-SOI technical partners in the Asian market include Taiwan processor IP supplier crystal heart Science and Technology (Andes), as well as Rickchip, Shanghai Fudan Microelectronics Group, as well as Hunan Goke Microelectronics.
These vendors support the common reasons for FD-SOI technology, are for the Internet of Things (IoT) chip; in which Crystal Heart Technology embraces the FD-SOI decision is particularly eye-catching. Crystal Heart and GlobalFoundries recently announced that the 32-bit CPU core of crystalline has used the latter 22 nano FD-SOI technology (22FDX). GlobalFoundries pointed out that 22FDX is applied to Internet, mainstream mobile communications, RF links and networks, etc. It is a combination of optimization performance, power consumption and cost.
Lin Zhiming, General Manager of Crystal Heart, said in an interview with EE Times, FD-SOI: "will help us promote ultra-low power applications, such as Internet of Things, mobile phones, low-power 5G, and battery-powered consumer electronic equipment ... and many more."
Shareholders include crystallographic technology, including Mediatek, and its CPU core authorized business has found sufficient space in ARM's large market, which can be used to touch screen controllers, Wi-Fi, Bluetooth , FM and GPS controllers, as well as Internet sensor hub. And the Internet of Things application chip also uses the IP of crystalline heart. Be
Lin Zhiming said that FD-SOI and crystalline technology development direction is unanimously: "Our core locks low power, high efficiency, and is widely adopted in Wi-Fi, Bluetooth wireless equipment and Internet of Things equipment;" For example The core of N9 and N13 has been focused on the connection application. The N10 / D10 core is applied to image processing, N7, N8, N9, N10, are also applied to various Internet accessories such as wearable devices, smart sensors, and the like.
"Now, with our next-generation core N25 (32), NX25 (64-bit) will support the RISC-V architecture and cooperate with GlobalFoundries, we will bring more advantages to customers in the global market;" Lin Zhiming further explained: " In consumer electronic applications, FD-SOI can provide a wide range of performance and power options, for battery-powered equipment, for use with BODY Bias. "
He pointed out that this also applies to touch screen controllers because: "Although the work cycle of the touch screen controller is short, it takes a lot of calculation performance when active multi-finger touch operation, but because of the terminal action device Features, most of the time requires very low power consumption. "
Lin Zhiming summary pointed out: "The FD-SOI terminal target market is just consistent with our product line. We have many low-level cores such as N7, N8 and N9 have been adopted in those markets. We will be in the near future. Seeing more chips containing the core-containing core processor using FD-SOI process. "
FD-SOI technology Other progress
At the same time, Globalfoundries announced that there are three Chinese customers to adopt their latest 22FDX process technology, including Shanghai Fudan Microelectronics will adopt the platform design and development server, AI and intelligent networked equipment products in 2018, and Ruixin will use the process. Design ultra-low power Wi-Fi intelligent SOC and high-performance AI processors, the national micro-consumption plan 22FDX in the new generation of Internet of Things chips.
Globalfoundries have previously announced a new 12-inch wafer factory in Chengdu (FAB 11), which is expected to be completed in early 2018.
France's SOI and FD-SOI wafer vendor Soitec announced that its 2018 and 2019 accounting year will invest 40 million euros (about $ 46.5 million), increase the Yield of the FD-SOI wafer (12 吋) to one 400,000 pieces; the company announced in Singapore's wafer for the Singapore's quarantine, the goal is "closer to customer demand."
SOITEC said that this is the first phase of the company's production of FD-SOI wafer production in Singapore, which will provide a source of FD-SOI substrate supplied with multiple bases of customers in the future to respond to long-term needs of the market; Soitec also announced GlobalFoundries signed a five-year agreement to ensure adequate advanced FD-SOI wafer supplied to the latter.
GlobalFoundries and Samsung are trying to put data processing, linkability and memory, etc., integrate on the FD-SOI single-chip; GlobalFoundries indicates that its 22-nanometer FD-SOI platform has supported EMRAM technology, which is a wide range of consumer and industries. Apply embedded memory provides embedded memory schemes.
Samsung also announced the first successful phrase EMRAM test chip on 28FDS technology; the company has more than 40 products that have been successfully phrase with FD-SOI process, including IT networks, servers, consumer products. , Internet of Things equipment and vehicle equipment.
