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 12):
The method of  claim 11 , further comprising setting a voltage Vge with which a gate is driven, in accordance with the equation:\n Vge=V 1/ K  wherein V1 is a voltage with which the second gate in the reference structure is driven, the voltage V1 being equal to 15V in the case that the high-voltage insulated gate type bipolar semiconductor device having the reference structure is in an on-state condition, K is the scaling ratio being equal to or greater than three.
