Method of forming a semiconductor device using selective epitaxial growth

摘要

A method of forming a semiconductor device using selective epitaxial growth (SEG) is provided. This method includes forming an insulating layer pattern having a window on a semiconductor substrate. The window exposes a predetermined region of the semiconductor substrate. The substrate having the window is cleaned, thereby removing any native oxide layer on the exposed substrate. The cleaned substrate is oxidized. Accordingly, a sacrificial oxide layer is formed thereon. The sacrificial oxide layer is removed. Thus, the exposed substrate has substantially no crystalline defects. A single crystalline semiconductor layer is then grown on the exposed substrate using SEG.
