Abstract:
A semiconductor device including: drift regions formed on a semiconductor substrate; gate trench portions extending in predetermined extending directions from a semiconductor substrate upper surface; first and second mesa portions being in direct contact with one and the other sides of a gate trench portion side wall respectively; accumulation regions being in direct contact with the gate trench portions, above the drift regions, and having doping concentration higher than drift region concentration; a base region being in direct contact with the gate trench portions, above the accumulation regions; emitter regions being in direct contact with the one side wall of a gate trench portion on a semiconductor substrate upper surface in the first mesa portion, and having doping concentration higher than drift region concentration; and electrically floating second conductivity type floating regions provided spaced from the gate trench portion below the base region in the second mesa portion is provided.

Claim (Index 1):
A semiconductor device comprising:\n a first conductivity type drift region formed on a semiconductor substrate; a gate trench portion provided reaching from an upper surface of the semiconductor substrate to an inner part of the semiconductor substrate and provided extending in a predetermined extending direction from the upper surface; a first mesa portion being in direct contact with one of two side walls of the gate trench portion; a second mesa portion being in direct contact with an opposite side of the one of two side walls of the gate trench portion; a first conductivity type accumulation region having doping concentration higher than that in the drift region, which is provided being in direct contact with the gate trench portion above the drift region; a second conductivity type base region provided being in direct contact with the gate trench portion above the accumulation region; a first conductivity type emitter region having doping concentration higher than that in the drift region, which is provided on the upper surface of the semiconductor substrate such that it is in direct contact with the one of two side walls of the gate trench portion in at least the first mesa portion; and an electrically floating second conductivity type floating region provided below the base region in the second mesa portion and spaced from the gate trench portion.
