摘要
A method of forming a semiconductor structure includes patterning one or more fin structures disposed over a top surface of a substrate, a given one of the fin structures comprising a first semiconductor layer comprising a first material disposed over the top surface of the substrate and a second semiconductor layer comprising a second material disposed over a top surface of the first semiconductor layer. The method further includes forming a liner over the one or more fin structures, and performing an anneal process to form one or more nanoscale features in a top surface of the second semiconductor layer. The second material exhibits enhanced diffusion, relative to the first material, at an interface of the liner and sidewalls of the given fin structure.
