ABSTRACT:
A cellular MOSFET device has a cellular area (CA) comprising active MOSFET cells, and one or more Schottky diode areas (SA) accommodated within a deep end region (15) at a lateral boundary of this cellular area (CA). This deep end region (150) is laterally divided so as to accommodate the diode area (SA) therein. A diode portion (14d) of the first conductivity type of the drain region (14) extends upwardly through the laterally-divided deep end region (150) that is of the second conductivity type. The Schotty barrier (100) formed with this diode portion (14d) terminates laterally in the laterally-divided portions (150deep end region (150) which serve as a guard region and field-relief region for the Schottky diode.
