Abstract
A device includes an epitaxial region extending into a front surface of a chip. A portion of the chip adjacent the epitaxial region defines a collector. A gate is provided in a trench extending into the epitaxial region from the front surface. An emitter includes a body extending into the epitaxial region at a first side of the trench and a source extending into the body region from the front surface at the trench. A dummy emitter extends into the epitaxial region from the front surface at a second side of the trench opposite said first side. The dummy emitter lacks the source. The gate extends along a first wall of the trench facing the emitter region. A dummy gate is formed in the trench in a manner electrically isolated from the gate and extending along a second wall of the trench opposite said first wall.
