ABSTRACT:
Chemical vapor deposition methods use trisilane and a halogen-containing etchant source (such as chlorine) to selectively deposit Si-containing films over selected regions of mixed substrates. Dopant sources may be intermixed with the trisilane and the etchant source to selectively deposit doped Si-containing films. The selective deposition methods are useful in a variety of applications, such as semiconductor manufacturing.
