Provided is a metal oxide semiconductor with an inverted U-shaped recess formed therein, the recess having two relatively deep outside channels and an interconnecting relatively shallow channel. The recess is filled with polycrystalline silicon gate material, and when biased, a conductive region is formed alongside an outside channel. Also provided also is a method of forming such an inverted U-shaped recess in a metal oxide semiconductor.
