Abstract
A silicon buffer layer selected from undoped silicon, p-doped silicon or a multilayered stack of, in any order, undoped silicon and p-doped silicon is provided between an nsilicon layer and an oxide layer of an SOI substrate. The presence of the silicon buffer layer reduces electron injection into the oxide layer during device processing which requires an electric field.
