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 12):
A super junction metal oxide semiconductor bipolar transistor comprising:\n a set of source portions; a set of body contact portions, each body contact portion of the set of body contact portions adjacent a corresponding source portion of the set of source portions; a set of extended p-columns, each P\u2212column of the set of P\u2212columns beneath a corresponding body contact portion of the set of body contact portions; a set of N\u2212columns, each N\u2212column of the set of N\u2212columns adjacent one extended P\u2212column of that set of extended P\u2212columns; an N\u2212drift region beneath the set of extended P\u2212columns, the set of first N\u2212columns and the set of second N\u2212columns; an N\u2212type field stop layer beneath the N\u2212drift region; a P+collector layer beneath the N\u2212drift region; a set of N+drain gaps in the P+collector layer; and, whereby the set of N+drain gaps enable a transition of unipolar conduction to bipolar conduction at a pre-determined current density.
