Patent ID: 7626231

Claim:
An Integrated Circuit having a plurality of trench MOSFET and a plurality of Junction Barrier Schottky rectifier comprising: a substrate of the first conductivity type; an epitaxial layer of said first conductivity type over said substrate, said epitaxial layer having a lower doping than said substrate; a trenched MOSFET comprising a trenched gate surrounded by a source region encompassed in a body region above a drain region disposed on a bottom surface of a substrate, wherein said trench MOSFET further comprising: an insulation layer covering said integrity circuit with a source-body contact trench opened there through said source region and extended into body regions and filled with a contact metal plug therein, wherein a gate oxide lining said trenched gate and a doped polysilicon within said trench and overlying the gate oxide; and a junction barrier Schottky rectifier extending into said epitaxial layer and having a barrier layer lined in said contact trench filled with contact metal plug and between a pair of adjacent P-bodies.
