Abstract:
A method for fabricating a high-voltage insulated gate type bipolar semiconductor device by comparing to a reference structure of the same includes determining a width S of a mesa region in which the gate insulating film and the MOS transistor are formed, and a trench depth D T , based on a scaling ratio K, in comparison with a second width and a second trench depth of the reference structure, and setting a cell width 2W of the high-voltage insulated gate type bipolar semiconductor device to be equal in length to a second length of the reference structure, the scaling ratio K being defined as K=Y/X, where X indicates a size of a target portion to be miniaturized in the high-voltage insulated gate type bipolar semiconductor device, and Y indicates a size of a target portion to be miniaturized in the reference structure.

Claim (Index 15):
The method of  claim 1 , wherein the step of implanting an impurity for forming the second conductivity type emitter layer is carried out prior to the step of implanting an impurity for forming the second conductivity type base layer and the second conductivity type layer having a non-fixed potential.
