Assignee: IDEAL POWER INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A semiconductor device comprising:
an upper base region associated with a first side of a substrate of semiconductor material;
an upper-CE trench defined on the first side, the upper-CE trench defines a proximal opening at the first side and a distal end within the substrate;
an upper collector-emitter region disposed at the distal end of the upper-CE trench;
a lower base region associated with a second side of the substrate; and
a lower collector-emitter region associated with the second side;
a lower-CE trench defined on the second side, the lower-CE trench defines a proximal opening at the second side and a distal end within substrate; and
wherein the lower collector-emitter region is disposed at the distal end of the lower-CE trench.
