Slater Matsil, LLP
Non-planar transistors and methods of fabrication thereof
Non-planar transistors and methods of fabrication thereof are described. In an embodiment, a method of forming a non-planar transistor includes forming a channel region on a first portion of a semiconductor fin, the semiconductor fin having a top surface and sidewalls. A gate electrode is formed over the channel region of the semiconductor fin, and an in-situ doped semiconductor layer is grown on the top surface and the sidewalls of the semiconductor fin on opposing sides of the gate electrode using a selective epitaxial growth process. At least a part of the doped semiconductor layer is converted to form a dopant rich region.
