Abstract:
A method of manufacturing a semiconductor device, including implanting hydrogen atoms from a second principal surface of a semiconductor substrate, forming a plurality of second semiconductor layers that each have a carrier concentration higher than that of the first semiconductor layer and that have carrier concentration peak values at different depths from the second principal surface of the semiconductor substrate, applying a heat treatment process to promote generation of donors from the hydrogen atoms, implanting an impurity from the second principal surface of the semiconductor substrate, forming a third semiconductor layer in the semiconductor substrate at the second principal surface thereof, and applying another heat treatment process to locally heat the semiconductor substrate, so as to reduce the carrier concentration at an interface between the third semiconductor layer and the second semiconductor layer adjacent to the third semiconductor layer.

Claim (Index 6):
The method of manufacturing a semiconductor device according to  claim 1 , wherein\n the second heat treatment process includes decreasing the carrier concentration at the interface between the third semiconductor layer and the one second semiconductor layer, so that the decreased carrier concentration is no larger than a carrier concentration at an interface between the one second semiconductor layer and another one of the second semiconductor layers adjacent to the one second semiconductor layer.
