Abstract:
1. A Fin field effect transistor (FinFET) comprising: a fin-channel body over a substrate; a gate electrode disposed over the fin-channel body; and at least one source/drain (S/D) region disposed adjacent to the fin-channel body, the at least one S/D region being substantially free from including any fin structure, wherein the substrate has a portion between a first isolation region and a second isolation region, the at least one S/D region includes an epitaxially-grown region, and the epitaxially-grown region is disposed over the portion of the substrate, and the first isolation region has a corner where a surface of the first isolation region and an interface between the first isolation region and the portion of the substrate intersect, the portion of the substrate has a tip where a surface of the portion of the substrate and the interface between the first isolation region and the portion of the substrate intersect, and the corner is substantially adjacent to the tip.
