Abstract
A method of forming a self-aligned gettering region within an SOI substrate is provided. Specifically, the inventive method includes the steps of forming a disposable spacer on each vertical sidewall of a patterned gate stack region, the patterned gate stack region being formed on a top Si-containing layer of an SOI substrate; implanting gettering species into the top Si-containing layer not protected by the disposable spacer and patterned gate stack region; and removing the disposable spacer and annealing the implanted gettering species so as to convert said species into a gettering region.
