INDUSTRY BUZZ

The myvu™ personal media viewer from MicroOptical that created such a huge buzz at its US/Macworld debut in January is built around Kopin’s high speed, low power, SOI-based CyberDisplay. Marketed as the ultimate iPod™ video accessory in the U.S., it was introduced in Europe last fall by France Telecom’s Orange mobile video service, to accompany the Samsung D600 mobile phone.



Oki Electric recently announced that it had developed a GaN-HEMT on a lowcost silicon substrate, achieving a world record for transconductance rating. It is planned for deployment in WiMAX products in 2007.

Sony Corporation, Sony Computer Entertainment Inc., Toshiba and IBM have announced a new, five-year phase of their joint technology development alliance to focus on fundamental research related to advanced process technologies at 32 nanometers and beyond.

Analog Devices recently announced what it said was the industry’s first differential amplifier (diff amp) to achieve the ultra low distortion levels needed to drive high-speed ADCs (up to 380 MHz) for next generation 3G and 4G cellular and broadband WiMAX wireless infrastructure equipment. The company credits it specialized silicon germanium (SiGe) silicon-on-insulator (SOI) process technology for the ultra low distortion.

IBM and AMD have detailed their progress in 65-nm technology, in which they have successfully combined embedded SiGe with Dual Stress Liner and Stress Memorization technology on SOI wafers, resulting in a 40 percent increase in transistor performance compared to similar chips produced without stress technology, while controlling power consumption and heat dissipation. The two have also announced that they are broadening and extending their technology alliance, adding early-stage research on critical, emerging technologies targeted at 32 and 22 nm, through 2011.

With momentum gathering for its SOIbased Opteron,™ AMD is continuing its charge into supercomputers. It is extending its relationship with Cray and is teaming up with Sun at Tokyo Tech in the creation of Japan’s largest supercomputer. With 10,480 AMD Opteron™ processor cores, it is expected to be one of the five largest supercomputers in the world as ranked by Top 500® (http://www.top500.org) in Summer 2006.

Freescale announced an SOI-based Inverted T Channel-Field Effect Transistor (ITFET) device. The company says it heralds a new breed of dramatically smaller, higher performing semiconductors that require less power, and that offer better manufacturability than FinFET transistors and other vertical devices.

SOI has made Hitachi’s newest
"µ-Chip"
the world’s smallest, thinnest RFID IC chip ever. SOI prevents interference between devices, enabling higher integration on a smaller area, increasing the number of chips fabricated on a single wafer and increasing productivity by more than four times. At 7.5-µm thick, this SOI-based chip is 1/8th the thickness of its bulk predecessor. This was achieved by the complete removal of the silicon layer on the reverse side of the SOI substrate on which the circuit is fabricated.



Soitec has announced a 350 million Euro strategic investment plan for a new, 300-mm SOI wafer plant, which will have a capacity of 1 million wafer starts per year when fully equipped. A worldwide location review is underway, with construction expected to start in the 06/07 financial year.

Starting Q3 06, IBM will start shipping a blade computing system based on the Cell Broadband Engine™ for graphicintensive, numeric applications.

Chirac Awards Innovation Prize to Soitec

During an Elysée ceremony, the French president cited the company’s international growth and employment creation.


At a ceremony held at the presidential Elysée Palace in March, French President Jacques Chirac awarded Soitec the “2006 Boldness and Creativity Award” (Prix de l’Audace Créatrice).

The prize, awarded yearly, recognizes the achievements of a listed company that is particularly dynamic, that has posted strong growth and profitability, and also has created significant employment opportunities in France. Initially created in 1995, its goal is to promote the entrepreneurial spirit and support bold initiatives.

Accepting on behalf of the company, Soitec President and co-founder André-Jacques Auberton-Hervé said, “This honor rewards the efforts of everyone at our company – that in less than 14 years, Soitec should become a veritable engine for growth and the top player in its market.”

Soitec was created in 1992 by Jean-Michel Lamure and André-Jacques Auberton-Hervé, two research engineers from the French national CEA/Léti electronics lab, to commercialize Smart Cut™ wafer engineering technology. Listed on the Euronext Paris stock exchange, Soitec posted 04/05 sales of 138.9 million Euros. With sales growing by about 80% in the current fiscal year, the company now counts over 750 employees and an 8% R&D investment rate.

The 2006 Boldness and Creativity Award was chosen by a 14-person jury lead by the Finalac Group, and comprising the presidents of companies such as AXA, Lagardère, Dassault, Group Danone, SEB, Essilor, Club Med and Renault.
 

IEEE/EDS Accolades for SOI Innovators

Top honors go to advanced substrate pioneers – again.


For the second year in a row, the IEEE Electron Devices Society (EDS) gave the J.J. Ebers Award for "...outstanding technical contributions to electron devices" to an SOI pioneer. The 2005 honor went to Bijan Davari of IBM, now Vice President of Next Generation Computing Systems/Technology.

The awards program noted that Dr. Davari and his team at IBM’s Semiconductor Research and Development Center were
responsible for the definition and development of pioneering technologies such as SOI, among their many accomplishments. The previous year’s award went to SOI modeling innovator Jerry G. Fossum.

Another top EDS honor, the George E. Smith Award, went to the MIT and Amberwave team of Zhi-Yuan Charles Cheng, Arthur J. Pitera, Minjoo Larry Lee, Jongwan Jung, Judy L. Hoyt, Dimitri A. Antoniadis and Eugene A. Fitzgerald for their paper entitled, “Fully Depleted Strained-SOI n- and p-MOSFETs on Bonded SGOI Substrates and Study of the SiGe/BOX Interface.” The paper covered FD-SGOI research conducted at MIT.
 

IBM + SOI Yield More Honors

Company received top White House medal and SI Fab of the Year.


Recently, IBM has been lining up awards for technology leadership, often citing the company’s work in SOI.

IBM’s 300-mm, SOI-enabled Building 323 in East Fishkill, NY, was selected as the Semiconductor International 2005 Top Fab Award winner. According to the publication, "IBM has produced products at competitive cycle times, cost and defect densities, with an excellent ‘first-time-right’ track record."

At the end of 2005, IBM also received the 2004 National Medal of Technology from the U.S. Department of Commerce and the Technology Administration. The award, which is the nation’s highest honor for leading innovators, recognized IBM for over four decades of innovation in semiconductor technology, specifically citing SOI among the advances.

What’s After Silicon?

By Dr. Chris Werkhoven
VP Strategic Marketing, ASM America
www.asm.com

For each technology node, those in the substrate world have to be ready with options years in advance of their customers. ASM describes developments in germanium epitaxy that could enable the industry to choose a GeOI future.


In the silicon device industry, new materials have to be introduced to assure IC performance improvement from one technology node to the next.

Soitec’s contribution has been to re-invent the silicon wafer through the development and production of SOI wafers. Most recently, “strained SOI” (sSOI) has been announced, developed in close collaboration with the ASM epitaxy and furnace product groups. sSOI will enable continuous performance improvement from the 45nm node onwards.

In addition to the Soitec “wafer scale” technologies, device and equipment makers have developed local strain processes using selective epitaxy of SiGe for PMOS and most recently also SiC for NMOS.

The Germanium Option
The combination of wafer-scale and local strain can be done up to the point where either the strain effect on the mobility “saturates” or where the strained epitaxial layers start to relax.

At that point, a new material for the channel region becomes unavoidable. The most obvious candidate is germanium because of its much higher mobility for both electrons and holes and because of its chemical similarity to silicon.

However, the worldwide availability of germanium-containing ores is very limited, ruling out a potential change to Ge wafers. To circumvent this limitation, ASM developed an innovative Ge on Si (GOS) process whereby only a thin epitaxial Ge layer is formed on a standard Si substrate.

High quality growth was demonstrated, and further optimization ensured a surface roughness close to what is needed for CMOS processing.

GOS wafers are a natural starting material for Smart Cut™-based manufacturing of Ge on insulator on silicon substrates (GeOI) and can be supplied in any wafer size at much lower cost than Ge wafers. Such layers are now being evaluated not only for CMOS device manufacturing but also for optoelectronic applications.
Also of interest is the fact that Ge can be used as a lattice-matched substrate for GaAs, which has an even higher mobility than Ge. With such a substrate wafer, other III-V materials will become available to integrate unique electronic and optoelectronic capabilities on a Si wafer platform, enabling new device technologies while using cost-effective, large diameter wafers and state of the art production tools.

Z-RAM Ultra-Dense Memories Remove Last Barrier to Entry for SOI

By Jeff Lewis
VP Marketing, Innovative Silicon
www.z-ram.com

ISi’s memory technology helps designers achieve speed increases and power savings at no extra cost.

It is well-accepted that SOI processing offers significant benefits in terms of speed and low power. Moreover, as the industry moves to the 65 and 45nm nodes, many analysts predict that bulk CMOS – so long the technology of choice – will be unable to scale due to inherent issues such as leakage, forcing system-on-a-chip (SoC) and microprocessor manufacturers to shift to SOI. Taking these factors into account, Gartner-Dataquest predicts a CAGR of 41.2 percent for SOI wafers between 2002 and 2008, and many leading companies such as AMD are already delivering chips built on SOI technology.

One of the last remaining impediments preventing companies from adopting SOI is cost. However, with the introduction of Z-RAM (Zero Capacitor DRAM) memory technology by Innovative Silicon Inc. (ISi), this last barrier is removed. Z-RAM memories are so dense – up to twice the density of existing embedded DRAM and five times denser than current embedded SRAM – that the typical processed wafer cost penalties of 8 to 15 percent that are usually associated with SOI are more than offset by the financial savings that can be realized by smaller die sizes.

SOI is already a great choice, and when used in combination with ISi’s Z-RAM memory IP, not only can designers achieve speed and power improvements, but they can save money, too. Depending on how much memory is put on-chip, the die cost of SOI + Z-RAM will be 10%-40% cheaper than the same chip designed in bulk CMOS.

By removing the cost obstacle, Z-RAM is enabling SOI to move deeper into the mainstream.
