Abstract

In this paper the influence of spacer material (S13N4, S1O2 or vacuum) on Ultra Thin Body and Buried Oxide (UTBB) SOI nMOSFET for underlapped and self-aligned drain engineering devices are studied by bi-dimensional numerical simulations. It is observed that the short length underlap devices are more influenced by spacer material. On the other hand, self-aligned does not present much spacer material dependence for the studied dimensions.
