Abstract:
A field effect transistor comprising:a semiconductor substrate having a pair of spaced apart void regions filled with a dielectric, said dielectric in said void regions and said substrate providing a first planar surface having a pair of spaced apart regions of said dielectric with the substrate disposed between said regions of said dielectric;a conductive drain region disposed solely on one of said pair spaced apart regions of said dielectric;a conductive source region disposed solely on the other of said pair of spaced apart regions of said dielectric;a region of semiconductor material disposed on said substrate between said regions of said dielectric and intimate with said source region and said drain region, wherein said source region, said drain region and said region of semiconductor material each has a second surface coplanar with the second surface of the other of said source region, said drain region and said region of semiconductor material and remote from and non-coplanar with said first planar surface;a gate insulator layer having a planar outer surface disposed over said second surface; anda conductive gate body disposed on said gate insulator.
