    摘要: Processes for non-selectively forming one or more conformal silicon-containing epitaxial layers on recess corners are disclosed. Specific embodiments pertain to the formation and treatment of epitaxial layers in semiconductor devices, for example, Metal Oxide Semiconductor Field Effect Transistor (MOSFET) devices. In specific embodiments, the formation of a non-selective epitaxial layer involves exposing a substrate in a process chamber to deposition gases including a silicon source such as silane and a higher order silane, followed by heating the substrate to promote solid phase epitaxial growth.
