Abstract

A process for forming a strained semiconductor layer. The process includes implanting ions into a semiconductor layer prior to performing a condensation process on the layer. The ions assist in diffusion of atoms (e.g. germanium) in the semiconductor layer and to increase the relaxation of the semiconductor layer. After the condensation process, the layer can be used as a template layer for forming a strained semiconductor layer.
