Last week, Japanese sources have reported serious problems with the establishment of GlobalFoundries facilities on 28-nm SOI-production on substrates. Supposedly they can lead to the transfer of production of Steamroller processors (in particular - CPU Kaveri) from 2013 to 2014, instead of which we are waiting for release of 32-nm processors on Richland Piledriver architecture (plus graphics GCN).
It should also be clear that the next generation of semiconductors will be produced during the so-called fully-depleted SOI (FB-SOI, fully-depleted SOI). According to Nunena, his company is ready for the release of 28-nm and 20-nm FB-SOI-plates of STMicroelectronics, as has other advanced technical processes based on SOI. In addition, the company is ready to supply 20-nm semiconductors for everyone. In continuation of the topic - company plans to release the first prototype 14-nm silicon with FinFET-transistors in the first or second quarter of the year.
GlobalFoundries previously reported that it intends to jump one year from 20-nm to 14-nm. During 2013 the company will produce 20-nm solutions, and in 2014 - immediately start production of 14 nm. The first software tool for the design of 14-nm semiconductor company GlobalFoundries has started to deliver to its customers in September. What is important, according to the words of Nunena, 14-nm (14XM) process technology will not use SOI-or FB-SOI-substrate.
