Abstract:
Methods and designs are provided for a vertical power semiconductor switch having an IGBT-with-built-in-diode bottom-side structure combined with a SJMOS topside structure in such a way as to provide fast switching with low switching losses (MOSFET), low on-resistance at low currents (SJMOS), low on-resistance at high currents (IGBT), and high current-density capability (IGBT).

Claim (Index 1):
A super junction metal oxide semiconductor bipolar transistor comprising:\n a source terminal; a gate terminal; a source portion connected to the source terminal; a body contact portion adjacent the source terminal; an extended p-column beneath the body contact portion; a first n-column adjacent a first side of the extended p-column; a second n-column adjacent a second side of the extended p-column; a n-drift region beneath the extended p-column, the first n-column and the second n-column; a n-type field stop layer beneath the n-drift region; a P+collector layer beneath the n-type field stop; an N+drain gap in the P+collector layer; a drain contact beneath the N+drain gap; and, whereby the N+drain gap enables low R ds (on) unipolar conduction at a low current density and bipolar conduction at a high current density.
