ABSTRACT:
A structure of power semiconductor device having dummy cells around edge of active area is disclosed. The UIS test result of said improved structure shows that failed site after UIS test randomly located in active area which means avalanche capability of the semiconductor power device is enhanced by implementation of the dummy cells.
