Viewpoint: FD-SOI supports Moore's Law
STMicroelectronics' Laurent Remont believes that when it comes to price, power, and performance, fully-depleted silicon-on-insulator is a viable option in the journey towards 10nm process technology.
Moore's Law-the semiconductor industry's ability to double the number of transistors it can put on a silicon chip every two years-is more than the technical ability to print twice as many transistors on the same size die. The principle implicitly recognised the substantial improvements in reducing power and increasing performance that has come with this doubling in density. Over the last 50 years, the industry has followed Moore's Law because all three legs of the stool-price, power, and performance-have moved together.
Now, while the semiconductor industry continues to validate Moore's Law for the foreseeable future, it is facing headwinds below 28nm, the current state of the art, as the technology gets more complicated and costs escalate. In this context of price, power, and performance, fully-depleted silicon-on-insulator (FD-SOI) comes into its own as the best option in the journey towards 10nm process technology.

For chip manufacturers, end-product manufacturers, and ultimately consumers, FD-SOI fulfills the triple-enablers of Moore's Law and is already a proven solution, with 28nm availability for mass production. ST is also developing 14nm FD-SOI and expecting mass production availability in 2015 and 10nm FD-SOI is in the R&D phase.
