Why SOI is the Future Technology of Semiconductors
January 6, 2014
Let’s start with the short answer - because:
A. SOI is cheaper to fabricate than FinFet with comparable performance, and it is easier and cheaper to build FinFet on SOI which then provides better performance.
B. SOI is the natural technology for monolithic 3D IC for all overlaying transistor layers, and monolithic 3D is the most effective path to keep Moore's Law
C. SOI, or better 'XOI', is the most efficient path for most of the new concepts such as alternate materials for transistor construction and other structures like nano-wires.
Let’s now elaborate and discuss each of these points.
