Methods of selectively forming epitaxial semiconductor layer on single crystalline semiconductor and semiconductor devices fabricated using the same
摘要：
In methods of selectively forming an epitaxial semiconductor layer on a single crystalline semiconductor and semiconductor devices fabricated using the same, a single crystalline epitaxial semiconductor layer and a non-single crystalline epitaxial semiconductor layer are formed on a single crystalline semiconductor and a non-single crystalline semiconductor pattern respectively, using a main semiconductor source gas and a main etching gas. The non-single crystalline epitaxial semiconductor layer is removed using a selective etching gas. The main gases and the selective etching gas are alternately and repeatedly supplied at least two times to selectively form an elevated single crystalline epitaxial semiconductor layer having a desired thickness only on the single crystalline semiconductor. The selective etching gas suppresses formation of an epitaxial semiconductor layer on the non-single crystalline semiconductor pattern.

在单晶半导体上选择性地形成外延半导体层的方法和使用其制造的半导体器件的方法中，单晶外延半导体层和非单晶外延半导体层形成在单晶半导体和非单晶 半导体图案，分别使用主半导体源气体和主蚀刻气体。 使用选择性蚀刻气体去除非单晶外延半导体层。 主要气体和选择性蚀刻气体交替地和重复地供应至少两次以选择性地形成仅在单晶半导体上具有期望厚度的升高的单晶外延半导体层。 选择性蚀刻气体抑制在非单晶半导体图案上形成外延半导体层。
