发明名称 Semiconductor process for modifying shape of recess
摘要 A semiconductor process includes the following steps. Two gates are formed on a substrate. A recess is formed in the substrate beside the gates. A surface modification process is performed on a surface of the recess to modify the shape of the recess and change the contents of the surface.

主权项 1. A semiconductor process, comprising: forming a gate on a substrate; forming a recess in the substrate beside the gate; forming a seeding layer covering on the recess; after forming the seeding layer, performing a surface modification process on the recess by importing at least a depositing gas and at least an etching gas; and forming an epitaxial structure in the recess.
