Low stray inductance power module
First Claim
1. A power module, comprising:
- a substrate including an insulating member and a patterned metallization on the insulating member, the patterned metallization being segmented into a plurality of spaced apart metallization regions, adjacent ones of the metallization regions being separated by a groove which extends through the patterned metallization to the insulating member;
a first power transistor circuit including a first power switch attached to a first one of the metallization regions and a second power switch attached to a second one of the metallization regions adjacent a first side of the first metallization region; and
a second power transistor circuit including a third power switch attached to the first metallization region and a fourth power switch attached to a third one of the metallization regions adjacent a second side of the first metallization region which opposes the first side, the second power transistor circuit mirroring the first power transistor circuit.

Abstract
A power module includes a substrate including an insulating member and a patterned metallization on the insulating member. The patterned metallization is segmented into a plurality of spaced apart metallization regions. Adjacent ones of the metallization regions are separated by a groove which extends through the patterned metallization to the insulating member. A first power transistor circuit includes a first power switch attached to a first one of the metallization regions and a second power switch attached to a second one of the metallization regions adjacent a first side of the first metallization region. A second power transistor circuit includes a third power switch attached to the first metallization region and a fourth power switch attached to a third one of the metallization regions adjacent a second side of the first metallization region which opposes the first side. The second power transistor circuit mirrors the first power transistor circuit.
