TowerJazz Cites Strong RF-SOI Growth as Driving force in TX Fab Acquisition

With the acquisition of Maxim’s 8-inch fab in San Antonio, Texas, TowerJazz plans to quickly qualify its core specialty technologies, including its advanced Radio-Frequency Silicon-on-Insulator (RF-SOI) offering, to serve the substantial growth in demand from its customers. (See press release here.) The proposed purchase will expand TowerJazz’s current worldwide manufacturing capacity, cost-effectively increasing production by […]

Leti Develops 22nm FD-SOI Local-strain Techniques to boost performance and lower power consumption

CEA-Leti announced it has developed two techniques to induce local strain in FD-SOI processes for next-generation FD-SOI circuits that will produce more speed or lower power consumption and improved performance. (For more details, read the press release here.) Targeting the 22/20nm node, the local-strain solutions are dual-strained technologies: compressive SiGe for PFETs and tensile Si […]

RF-SOI Roars Back into the Headlines

Articles about chips built on RF-SOI technology are back in the headlines. What’s driving it? Data – lots of it, and at ever higher speeds, finding its way in and out of your mobile device. Bear in mind that we’re talking now about RF-SOI, which is not the same thing as RF in FD-SOI. These […]

Don’t miss EuroSOI-ULIS, 25-27 January 2016 in Vienna. Call for papers still open.

The 2016 Joint International EUROSOI Workshop and International Conference on Ultimate Integration on Silicon, aka EUROSOI-ULIS 2016 will be taking place January 25-27, 2016 in Vienna, Austria. The event will be hosted by the Institute for Microelectronics, TU Wien. The focus of the sessions is on SOI technology and advanced nanoscale devices. The organizing committee […]

RF-SOI vs. FD-SOI with RF – What’s the difference?

Is RF-SOI the same thing as RF on FD-SOI? No, it’s not. However, the runaway success of RF-SOI and the growing list of recent announcements related to FD-SOI with integrated RF has lead to some confusion in the press and social media. The two are different technologies, addressing different markets, and built on two very […]

Industry 1st: Leti Demos MEMS on 300mm Wafers – And Yes, They’re SOI

In what may be a first for the MEMS industry, CEA-Leti has manufactured micro-accelerometers on 300mm wafers, a development that could lead to significantly lower MEMS manufacturing costs. And yes, those 300mm wafers are SOI wafers. These are “thick” SOI wafers, with an insulating BOx (buried oxide) layer of 2µm, and top silicon of 220nm. […]
