Power semiconductor component with charge compensation structure and method for the fabrication thereof
摘要:
A semiconductor component with charge compensation structure has a semiconductor body having a drift path between two electrodes. The drift path has drift zones of a first conduction type, which provide a current path between the electrodes in the drift path, while charge compensation zones of a complementary conduction type constrict the current path of the drift path. For this purpose, the drift path has two alternately arranged, epitaxially grown diffusion zone types, the first drift zone type having monocrystalline semiconductor material on a monocrystalline substrate, and a second drift zone type having monocrystalline semiconductor material in a trench structure, with complementarily doped walls, the complementarily doped walls forming the charge compensation zones.
