Abstract:
1. A semiconductor device comprising: an IGBT structure provided in an IGBT area within a substrate; and a diode structure provided in a diode area within said substrate, wherein said IGBT area is adjacent to said diode area, a region of shortening lifetime of carriers is provided in said IGBT area and said diode area, and a density of articles of shortening lifetime of carriers in a sub-area that is within said IGBT area and adjacent to said diode area is higher than a density of articles of shortening lifetime of carriers in the other area that is within said IGBT area and separated from said diode area by said sub-area and said density of articles of shortening lifetime of carriers in said sub-area is higher than a density of articles of shortening lifetime of carriers in said diode area.
