Silicon on Insulator

Product Description: 

Silicon on insulator (SOI) technology refers to a structure of a thin silicon layer on an insulator, such as silicon dioxide. This structure separates the active silicon layer from the bulk substrate, the handle wafer, to improve device performance for CMOS devices and more flexible integration schemes for electronic, MEMS devoices.
