Abstract:
First and second p-type anode layers ( 2,3 ) are provided side by side on a drift layer ( 1 ). N-type cathode layer ( 5 ) and p-type cathode layer ( 6 ) are provided side by side below the drift layer ( 1 ). An n-type buffer layer ( 7 ) is provided between the drift layer ( 1 ) and the n-type cathode layer ( 5 ) and between the drift layer ( 1 ) and the p-type cathode layer ( 6 ). The first p-type anode layer ( 2,2 a, 2 b ) has a greater diffusion depth than a diffusion depth of the second p-type anode layer ( 3 ). The first p-type anode layer ( 2,2 a, 2 b ) has a greater impurity concentration than an impurity concentration of the second p-type anode layer ( 3 ). The n-type cathode layer ( 5 ) has a greater diffusion depth than a diffusion depth of the p-type cathode layer ( 6 ). The n-type cathode layer ( 5 ) has a greater impurity concentration than an impurity concentration of the p-type cathode layer ( 6 ).

Claim (Index 1):
