Abstract:
A method includes providing a structure having a substrate and a fin extending from the substrate, wherein the fin includes a first semiconductor material and has a source region, a channel region, and a drain region for a transistor; forming a gate stack over the channel region; performing a surface treatment to the fin in the source and drain regions, thereby converting an outer portion of the fin in the source and drain regions into a different material other than the first semiconductor material; etching the converted outer portion of the fin in the source and drain regions, thereby reducing a width of the fin in the source and drain regions; and depositing an epitaxial layer over the fin in the source and drain regions.

Claim (Index 21):
A method, comprising:\n providing a substrate and a fin extending from the substrate and through an isolation structure covering the substrate, wherein the fin includes a source region, a channel region, and a drain region for a transistor; forming a gate stack over the channel region; oxidizing top and sidewall surfaces of the fin in the source and drain regions; etching the oxidized top and sidewall surfaces of the fin to shrink a width and a height of the fin in the source and drain regions, wherein the sidewall surfaces of the fin in the source and drain regions are curved after the etching; and epitaxially growing a material layer covering the fin in the source and drain regions.
