Abstract:
1. A structure comprising: a silicon substrate including trench isolation extending from a top surface of said substrate into said substrate; a silicon body extending in a first direction on a top surface of said substrate, said silicon body including a channel region contained between first and second source/drains on opposite sides of said channel region, said first and second source/drains insulated from said substrate by a dielectric layer between said first and second source/drains and said substrate, a region of said dielectric layer contacting said trench isolation, a region of said substrate contacting said channel region; a gate electrode extending in a second direction, said second direction different from said first direction, said first and second directions parallel with said top surface of said substrate; a first region of a gate dielectric layer on said opposite sidewalls of said channel region between said gate electrode and said channel region a second region of said gate dielectric layer on said top surface of said substrate between said region of said substrate contacting said channel region and said trench isolation, said second region of said gate dielectric layer between said gate electrode and said substrate; and a dielectric capping layer on a top surface of said channel region between said gate dielectric layer and said channel region.
