Wondering what’s new, what’s hot and what’s next in the SOI and advanced substrate world? Check
out our Industry Buzz – now featuring regular updates.
In a blog entitled “FD-SOI Will Be Mainstream” (8 October 2014 – read it here), ElectronicsWeekly’s David Manners reports that the CEO of Synapse Design predicts FD-SOI will be a mainstream technology.
Synapse has been working in FD-SOI since 2011, has already taped out three designs and has more in the pipeline, the CEO told Manners. He sees a lot of activity coming from Japan and China in automotive and mobile as well as in network infrastructure.Posted October 17, 2014 - Share this Buzz
SOI wafer leader Soitec was awarded the Best Partnership Award by Sony Semiconductor. Soitec earned the recognition for outstanding support that has contributed to Sony’s success in the RF semiconductor market.
Soitec’s high-resistivity silicon-on-insulator (HR-SOI) wafers have long been a favorite of RF designers for 2G and 3G switches. But the company’s latest eSi substrates has taken off like wildfire, and are now used by all the major companies that make RF chips for smart phones. The eSI wafers enable much higher linearity and isolation, helping designers to address some of the most advanced LTE requirements at competitive costs. You can read more about the technical details of the wafers and how they were developed here and how they solve key challenges here.
“We are very honored to receive this award from Sony recognizing the long partnership between our companies,” said Bernard Aspar, senior vice president and general manager of Soitec’s Communication & Power Business Unit. “It demonstrates Soitec’s commitment to deliver the enabling substrates that support Sony’s RF devices business.”Posted October 17, 2014 - Share this Buzz

“ST needed a fast, practical method to ensure our IP would not be susceptible to noise issues, when implemented in complex, multi-million gate SoCs. We have also found we can optimize the power-supply requirements to IP in the knowledge that both the position and number of pins or bumps will be adequate for the IP as implemented,” said Pierre Dautriche, Physical IP & Mixed Design Solutions Director, Central CAD & Design Solutions, STMicroelectronics. “Extensive use here has proven WaveIntegrity as the most efficient and effective way to achieve these aims, allowing us to reduce risk in ways previously impossible. This capability is being extended to both our most advanced and older process nodes, and which we will also support for our own customers. ”
ST is using WaveIntegrity across groups designing complex IP for home and automotive devices. Getting a fast, initial picture of potential noise-related issues is vital in designing today’s complex SOCs and WaveIntegrity performs noise-analysis results right from the initial floorplan, as IP is delivered to the chip assembly team.
WaveIntegrity encourages noise-analysis results to be used during the first and subsequent floorplan stages, so that critical design decisions can be made early and at low cost. The analysis setup is then refined for the final floorplan revision to support any potential remaining noise-related design choices before final place & route.Posted September 26, 2014 - Share this Buzz
Revelations by semiwiki’s Eric Esteve that TSMC has filed a significant FD-SOI patent has generated a rush of speculation in the press and online forums. In his piece When TSMC advocates FD-SOI…, Esteve noted that TSMC’s patent for “Planar compatible FDSOI Design Architecture” (granted 14 May 2013) heralded the advantages as follows: “Devices formed on SOI substrates offer many advantages over their bulk counterparts, including absence of reverse body effect, absence of latch-up, soft-error immunity, and elimination of junction capacitance typically encountered in bulk silicon devices. SOI technology therefore enables higher speed performance, higher packing density, and reduced power consumption.”
In a subsequent article in Electronics Weekly entitled TSMC Developing FD-SOI, David Manners concluded, “Clearly all mobile IC houses are looking at FD-SOI as an option because of its lower power potential. The fact that TSMC is developing the technology suggests that a customer or customers have enquired about using FD-SOI…”.Posted September 17, 2014 - Share this Buzz
RF-SOI Pioneer Peregrine has announced new switches for wireless infrastructure and carrier-grade WiFi. The UltraCMOS® PE42442 and PE42452 high-isolation, multi-throw switches address emerging requirements in wireless infrastructure equipment (read press release here). The UltraCMOS® PE42424 RF Switch enables 802.11ac Wi-Fi access points to deliver faster data rates in high-density, bring-your-own-device environments, with 60 percent power handling increase and 75 percent smaller footprint (read press release here)
In his recent piece, A couple of misconceptions about FD-SOI (3 September 2014), semiwiki blogger and IP expert Eric Esteve corrects some assertions surfacing about FD-SOI. He reminds designers that to really benefit from FD-SOI, you want to leverage body-biasing. He explains how ST has automated the IP conversion process so it takes about half the time you’d normally expect. He also advocates FD-SOI for wearables and smartphones, as it provides both performance advantages and power savings.Posted September 11, 2014 - Share this Buzz
A thoroughly engaging and amusing LinkedIn Pulse piece by Bruce Kleinman comes down firmly on the side of 28nm FD-SOI. Entitled 28nm: Home Improvements (posted 13 August 2014), it’s subtitled, “Welcome to 28nm! Make yourself comfortable, we’re going to be here for awhile.” He says (among lots of other things, including astute observations about 3D), “…in my book 28nm FD-SOI offers very similar performance/power characteristics to 20nm bulk silicon.” Kleinman’s currently SVP at HMicro, which is doing SOC solutions for demanding wireless apps and IoT. He’s clearly got the street creds, arriving there by way of upper management at GlobalFoundries, Xilinx, HP, etc., having started out with a Stanford MSEE. A good read – recommended.Posted September 11, 2014 - Share this Buzz
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
