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 5):
The semiconductor device according to  claim 2 , wherein width of the floating region in the array direction is equal to width of the gate trench portion in the array direction of the gate trench portion.
