Monolithic MOSFET and Schottky diode device

摘要

A Schottky diode is integrated into a planar or trench topology MOSFET having parallel spaced source regions diffused into spaced base stripes. The diffusions forming the source and base stripes are interrupted to permit the drift region to extend to the top of the die and receive a Schottky barrier metal and the source contact. The MOSFET and Schottky share the same drift region, and the pitch between base and source stripes is not changed to receive the Schottky structure.
