Assignee: MAXPOWER SEMICONDUCTOR, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. A power semiconductor device, comprising:
a first and a second laterally-gated transistor both having a portion of a first-conductivity-type source region, a gate electrode which is capacitively coupled to a body region to selectably form a lateral channel therein, a first-conductivity-type drain extension region connecting said lateral channel to a common drain electrode, a vertically-extended source extension region connecting said source region to a common source electrode on the backside of the device, and a shorting strap connecting said source region to said vertically-extended source extension region;
wherein both said gate electrodes are electrically separate portions of a single thin film layer;
wherein the threshold voltage of said first laterally-gated transistor is less than the threshold voltage of said second laterally-gated transistor; and
wherein said first laterally-gated transistor has a width which is smaller than a width of said second laterally-gated transistor.
