Abstract:
1. A semiconductor structure, comprising: a semiconductor substrate including a single crystalline semiconductor material, said semiconductor substrate having a substrate orientation; a V-shaped groove with a ridge and a first crystallographic facet and a second crystallographic facet of said single crystalline semiconductor material, wherein said V-shaped groove is bounded by a shallow trench isolation structure and said first crystallographic facet and said second crystallographic facet are joined at said ridge; a channel located beneath said V-shaped groove, said channel located directly beneath a first portion of said ridge, a portion of said first crystallographic facet, and a portion of said second crystallographic facet; a source located directly beneath a second portion of said ridge, said source comprising a first portion of said single crystalline semiconductor material; a drain located directly beneath a third portion of said ridge, said drain and comprising a second portion of said single crystalline semiconductor material; a gate dielectric located on and above said channel; and a gate conductor located on said gate dielectric.
