Abstract:
Included are a semiconductor substrate, an emitter electrode formed on the semiconductor substrate, a gate electrode formed on the semiconductor substrate, a source layer of a first conductivity type formed on the semiconductor substrate, a base layer of a second conductivity type formed on the semiconductor substrate, a collector electrode formed under the semiconductor substrate, a plurality of active trench gates formed on a top-surface side of the semiconductor substrate and connected to the gate electrode, and a plurality of dummy trench gates formed on the top-surface side of the semiconductor substrate and not connected to the gate electrode. First structures, each including three or more of the active trench gates arranged side by side, and second structures, each including three or more of the dummy trench gates arranged side by side, are alternately provided.

Claim (Index 1):
A semiconductor device comprising:\n a semiconductor substrate; an emitter electrode formed on the semiconductor substrate; a gate electrode formed on the semiconductor substrate; a source layer of a first conductivity type formed on an upper side of the semiconductor substrate; a base layer of a second conductivity type formed on the upper side of the semiconductor substrate; a collector electrode formed under the semiconductor substrate; a plurality of active trench gates formed on a top-surface side of the semiconductor substrate and connected to the gate electrode; and a plurality of dummy trench gates formed on the top-surface side of the semiconductor substrate and not connected to the gate electrode, wherein first structures, each including three or more of the active trench gates arranged side by side, and second structures, each including three or more of the dummy trench gates arranged side by side, are alternately provided, and wherein the number of dummy trench gates is equal to or larger than the number of active trench gates.
