眾志成城，集氣聚威？IBM聯盟大動員，合縱連橫的格局浮現。

繼Globalfoundries向盟友Samsung授權14nm製程技術後，兩年前授權Globalfoundries使用28nm FD-SOI夢幻製程的盟友STMicro，也再度密技大公開，授權Samsung與SMIC使用其28nm FD-SOI製程技術。

　　We expect FD-SOI product revenues at the end of the year. In fact, I think that the major volume will start in production in the second quarter of next year. So this will be very material, as we said, because this is high-volume products for consumer and this is complex products, so is ASP products. So this will be really for 2015, starting from introduction in Q2.
　　Traditionally, our ASIC activity was for communication infrastructure. This activity is, we can say, is based normally on high-complexity products with low volume. Now, with this very low power performance of the FD-SOI, we have managed to win very high volume products for complex products, for complex applications. So this is products with significantly higher ASP than the normal -- than normal -- than other products. And of course, this will pay off when the production volume will start, as I said before, in Q2 2015, with a number of important customers.

FD-SOI能量大爆發，一向僅能依賴自家Crolles晶圓廠產能的STMicro，此番藉由新增韓、中的Samsung與SMIC兩位戰友，將拓寬產品出海口，擴大FD-SOI的生態系統，使其應用領域自通訊基建延伸至消費電子。STMicro信心滿滿此番FD-SOI的出擊，估計2014年底即會貢獻營收，2015年第二季會有大躍進；而Samsung預計在2015年首季投產28nm的FD-SOI晶圓產品。

現今STMicro的消費產品重心雖在機上盒市場，而非通訊IC，然在提供STMicro產能之餘，推測同時擁有14nm製程技術共享與FD-SOI授權的Samsung與Globalfoundries或將FD-SOI視為抗衡TSMC的28nm、20nm領先優勢的利器，甚至是14nm製程的加持。


This is an ideal solution for customers looking for extra performance and power efficiency at the 28nm node without having to migrate to 20nm. 28nm process technology is a highly productive process technology and expected to have a long life span based on well-established manufacturing capabilities. By adding FD-SOI to our technology portfolio, Samsung provides a full-spectrum of 28nm process offerings for our customers’ success.
- Dr. Seh-Woong Jeong, EVP of Samsung

If SOI is all that it's cracked up to be, why isn't Intel and others on it? I acknowledge its technical possibilities, but will we see a stampede [toward 28nm FD-SOI]? We haven't seen it yet and probably won't unless ST comes up with device that blows everyone away.
- Dean Freeman with Gartner

如此夢幻好康，有賴大咖Intel動向與STMicro產品來證實。
