Abstract:
A method for fabricating an anode-shorted field stop insulated gate bipolar transistor (IGBT) comprises selectively forming first and second semiconductor implant regions of opposite conductivity types. A field stop layer of a second conductivity type can be grown onto or implanted into the substrate. An epitaxial layer can be grown on the substrate or on the field stop layer. One or more insulated gate bipolar transistors (IGBT) component cells are formed within the epitaxial layer.

Claim (Index 4):
The method of  claim 2 , wherein a width of the first implant regions of the second conductivity type is much larger than a width of second semiconductor regions of the first conductivity type.
