An excellent article in SST details Leti’s monolithic 3D (M3D) technology, as presented at the SemiconWest 2014 Leti Day (read the full article here). Written by Brian Cronquest, MonolithIC 3D’s VP Technology & IP, the piece covers a presentation given by Olivier Faynot, Leti’s Device Department Director, about “monolithic 3D technology as the ‘solution for scaling’.” Cronquest puts the big picture in perspective, while providing plenty of technical information. He ends by reminding readers that this and other key work will be further detailed at the IEEE S3S Conference (S3S = SOI + 3D + Subthreshold Microelectronics) October 6-9, 2014 at the Westin San Francisco Airport (see the conference website here).Posted September 1, 2014 - Share this Buzz
Murata and Peregrine Semiconductor have entered into a definitive agreement under which Murata will acquire all outstanding shares of Peregrine not owned by Murata (read full press release here). Peregrine will become a wholly owned subsidiary of Murata and continue with its current business model of solving the world’s toughest RF challenges. Peregrine supplies many wireless markets, including: smartphones, test & measurement, automotive, public safety radio and wireless infrastructure. Peregrine will also provide Murata with a strong portfolio of Intellectual Property Rights (IPR) covering the entire RF-SOI front-end.
“Murata is the world’s leading RF module and filter provider, and we have benefited from our many years of partnership with them. The combination of Murata’s leading products with Peregrine’s leading-edge SOI products will position us to compete aggressively in our chosen markets,” said Jim Cable, PhD, Chairman and CEO of Peregrine Semiconductor. “As part of the Murata team, we will be able to expand our existing partnership and speed the industry’s transition to an integrated, all-CMOS RF front-end. We remain committed to providing leading solutions to customers in all our current markets. We have huge respect for Murata’s capabilities, and look forward to jointly accomplishing great things.”Posted September 1, 2014 - Share this Buzz

A new book entitled Silicon-On-Insulator (SOI) Technology, Manufacture and Applications (1st Edition) features contributions by experts at Soitec, GF, TSMC, Leti and more.
Billed as “a complete review of this rapidly growing high-speed, low-power semiconductor technology,” the book covers the entire SOI spectrum, from Moore to More than Moore. It goes into SOI wafer technology, electrical properties, modeling, PD-SOI, FD-SOI, FinFETs and junctionless transistors, RF, ultralow-power, photonics, memory, power and MEMS. (See Table of Contents here.) This book should be a central resource for those working in the semiconductor industry, for circuit design engineers, and for academics, as well as for electrical engineers in the automotive and consumer electronics sectors.
Silicon-On-Insulator (SOI) Technology, Manufacture and Applications is published by Woodhead Publishing, and is also available in print and ebook forms from major online retailers such as Amazon, Elsevier and Barnes & Noble. It was compiled and edited by Oleg Kononchuk, chief scientist at Soitec, France, and Bich-Yen Nguyen, a senior fellow at Soitec, USA.Posted August 8, 2014 - Share this Buzz
Soitec estimates that it has shipped enough of its eSI wafers to fabricate more than 1.4 billion RF front-end semiconductor devices. (Read the press release here.) The proprietary Enhanced Signal Integrity™ (eSI) substrates are now the substrate of choice for manufacturing cost-effective and high-performance radio-frequency (RF) devices providing a power boost for 4G /LTE applications.
For eSI, Soitec and the Université catholique de Louvain (UCL) developed a technique that adds a “trap-rich” layer underneath the buried oxide, which freezes the parasitic surface conduction that’s inherent in any oxidized silicon substrate. (The technical details are clearly explained in an excellent ASN post by the Soitec and UCL team leaders – click here to read it.) Using a set of very specific patents, Soitec applied proprietary technology and accumulated knowledge to build the new eSI product line.
This substrate provides a raft of advantages to RF design. Because the trap-rich layer is built into the substrate, it reduces the number of process steps and relaxes design rules, leading to a highly competitive performance and die cost, including a smaller area per function. RF designers can therefore integrate diverse functions such as switches, power amplifiers and antenna tuners with excellent RF isolation, good insertion loss, better thermal conductivity and better signal integrity than other technologies.

IBM Foundry Solutions announced a new SOI-based technology for RF called 7SW SOI. The company says it is designed for 30 percent better performance than its predecessor, 7RF SOI, with which IBM shipped over seven billion chips in the last three years. The new mobile phone chip technology can help device manufacturers provide consumers with extremely fast downloads, higher quality connections, and longer battery life than its highly successful predecessor, says an IBM spokesperson. The new technology is designed to take advantage of more frequency bands, taking phone manufacturers one step closer to the reality of creating a “world phone” that can be used anywhere.
Here are the key points:
- The new technology gives designers added flexibility, enabling them to develop chips that integrate more function or that take up to 30 percent less space, depending on design goals.
- The new technology is a hybrid 180nm/130nm technology base and devices optimized to accommodate aggressive LTE standards and demanding worldwide coverage requirements
- It is optimized for multi-band switching in next-generation smartphones.
- Poised to drive innovation in newer category of smart devices in the Internet of Things as the new technology is an ideal fit for high-band LTE and Wi-Fi 5.8 GHz band applications.
- Clients can exploit the technology advances offered by 7SW to develop solutions that enhance user experiences, including broader geographic mobility and faster data rates for high definition video.

SiTime, which leverages SOI for high-performance MEMS timing solutions, has introduced what it says is the smallest, lowest power 32 kHz TCXO (temperature compensated oscillator – read the press release here). With its tiny footprint and ultra-low power consumption, the SiT1552 MEMS TCXO enables a paradigm shift in the size and battery life of wearable electronics and Internet of Things (IoT); such benefits are not available from legacy quartz devices.
“The SiT1552 MEMS TCXO is 20% of the size and consumes 50% of the power of comparable quartz devices,” said Piyush Sevalia, executive vice president of marketing at SiTime. “Our MEMS enable new system architectures that offer higher performance, small size and longer battery life. With another industry first, we continue to revolutionize the timing industry with our breakthrough MEMS solutions.”

Soitec, the world leader in SOI wafer manufacturing, has hired a former Intel exec, Thom Degnan, to take on the job of VP of the company’s sales and bizdev for the Electronics Division in North America (read press release here). Soitec says that this strategic hiring supports the Electronics Division’s focus on mobile markets with FD-SOI wafers for digital electronics and RF-SOI wafers for RF applications.
His experience is clearly right in the sweet spot for Soitec. Prior to joining the company, Degan was vice president of business development for Intel’s Services Division and, prior to that, vice president and general manager of the Americas Region of Intel Mobile Communications. Previously he was vice president and general manager of the Americas Region of Infineon Technologies, Inc., where he was responsible for all sales, business development and marketing for the company’s Communications Division, which Intel acquired in 2011.
Degnan will be based in San Diego, California.Posted June 8, 2014 - Share this Buzz
