Abstract
Process for fabricating a semiconductor device including steps of providing a semiconductor substrate having formed thereon a semiconductor device; depositing over the semiconductor device a spacer layer, the spacer layer having a first hydrogen content; and applying a treatment to reduce the first hydrogen content to a second hydrogen content. The invention is particularly useful when applied to flash memory devices such as a charge trapping dielectric flash memory device.
