Abstract
A method for depositing a carbon doped epitaxial semiconductor layer comprises maintaining a pressure of greater than about 700 torr in a process chamber housing a patterned substrate having exposed single crystal material. The method further comprises providing a flow of a silicon source gas to the process chamber. The silicon source gas comprises dichlorosilane. The method further comprises providing a flow of a carbon precursor to the process chamber. The method further comprises selectively depositing the carbon doped epitaxial semiconductor layer on the exposed single crystal material.
