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 8):
The semiconductor device according to  claim 1 , further comprising:\n 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 in the second mesa portion, such that it is in direct contact with said the other side wall of the gate trench portion, wherein\n the floating region does not exist in at least a part below the emitter region provided in the second mesa portion, in a depth direction of the semiconductor substrate.
