[0083] like figure 2 As shown, it is a schematic structural diagram of the planar power semiconductor device according to the second embodiment of the present invention; compared with the first embodiment of the present invention, the planar power semiconductor device according to the second embodiment of the present invention has the following features:
[0084] Under the condition that the total doping dose of the drift region 101 is kept unchanged, the drift region 101 is divided into a plurality of drift sub-regions 101a in the lateral direction, and the doping concentration of each drift sub-region 101a is different The setting of the doping concentration of the drift sub-region 101a regulates and regulates the surface electric field of the drift region 101 to make the surface electric field distribution of the drift region 101 uniform. figure 2 , each of the drift sub-regions is individually marked with a mark 101a.
[0085] The widths of the drift sub-regions 101a ar...
