Abstract:
A method includes forming a semiconductor fin over a substrate; forming a helmet stack on a top surface of the semiconductor fin; forming a spacer layer over the helmet stack and on opposite sidewalls of the semiconductor fin; and etching the helmet layer and the spacer layer to expose the top surface and the sidewalls of the semiconductor fin.

Claim (Index 15):
The method of  claim 13 , wherein removing the un-doped vertical portion of the amorphous silicon layer comprises an etching process, and the doped horizontal portion of the amorphous silicon layer has higher etch resistance to an etchant used in the etching process than that of the un-doped vertical portion of the amorphous silicon layer.
