Sounds Janine...it would be good to get a comment from them what is so special about Sapphire...I remember taking my grad courses 30 years ago when SoS (silicon on sapphire) was deemed to be the future of semiconductors ;-)...but then SoI happened
IBM has been using SiGe process for several years now...and 60 Gzh switches were announced way back too...so the technology has been developed long time ago, this is just announcement of trying to milk more dollars before teh technology becomes absolete...I doubt IBM will be investing more R&D into this
IBM is able to make switches for 60 GHz and above on 300mm wafer, that will be a great benefit to the wireless and wired areas. It will lead all other companies in the field and in the world. It is hope that this may save IBM from selling this unit.
I'm surprised you didn't mention silicon on sapphire as a competitive process for RF chips. Peregrine Semiconductor has had some impressive success with that. How does the IBM SOI process compare to SOS?
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
