Semiconductor devices including an epitaxial layer with a slanted surface

Abstract:

A method of fabricating one or more semiconductor devices includes forming a trench in a semiconductor substrate, performing a cycling process to remove contaminants from the trench, and forming an epitaxial layer on the trench. The cycling process includes sequentially supplying a first reaction gas containing germane, hydrogen chloride and hydrogen and a second reaction gas containing hydrogen chloride and hydrogen onto the semiconductor substrate.

Abstract(Chinese):

制造一个或多个半导体器件的方法包括在半导体衬底中形成沟槽，执行循环过程以从沟槽去除污染物，以及在沟槽上形成外延层。循环过程包括将含有锗烷，氯化氢和氢的第一反应气体和含有氯化氢和氢的第二反应气体依次提供到半导体衬底上。
