Abstract:
A p + -type anode region that forms a contact of an anode electrode on a front surface of a semiconductor substrate and a p + -type starting substrate of a rear surface of the semiconductor substrate is formed on the front surface of the semiconductor substrate, whereby an up-anode type vertical diode is configured. The semiconductor substrate has a p − -type epitaxial layer stacked on the p + -type starting substrate, and a p-type transition layer in a surface layer of the p − -type epitaxial layer, facing the p + -type starting substrate. A p-type anode diffusion region is provided between a p + -type surface anode region and the p-type transition layer, and contacts the p + -type surface anode region and the p-type transition layer. A p-type impurity concentration of the p-type anode diffusion region decreases from an interface with the p + -type surface anode region toward an interface with the p-type transition layer.

Claim (Index 9):
The semiconductor module according to  claim 7  and further comprising\n an electrode layer provided on the front surface of the second semiconductor chip, wherein \n the rear side of the first semiconductor chip is insulated from the electrode layer of the second semiconductor chip by the insulating film.
