Abstract:
A power semiconductor device includes a substrate, a main body and an electrode unit. The main body includes an active portion, an edge termination portion surrounding the active portion, and an insulating layer disposed on the edge termination portion. The edge termination portion includes a first-type semiconductor region, and a plurality of spaced-apart second-type semiconductor segments distributed in the first-type semiconductor region and arranged at intervals along a Y-direction directing from the insulating layer toward the substrate, and an X-direction directing from the active portion toward the edge termination portion. The electrode unit includes a first electrode and a second electrode.

Claim (Index 6):
The power semiconductor device of  claim 1 , wherein said second-type semiconductor segments of said edge termination portion have varying second-type doping concentrations that vary along the Y-direction, a second-type doping concentration difference between two adjacent ones of said second-type semiconductor segments being less than 10%.
