Abstract:
A reverse conducting IGBT device and a method for manufacturing the reverse conducting IGBT device are provided. The method includes: forming, based on a semiconductor structure including an IGBT cell region and a fast recovery diode cell region which are separated from each other, a copper electrode layer on an upper surface of the IGBT cell region; performing ion implantation on the semiconductor structure by using the copper electrode layer as a barrier layer, for controlling minority carrier lifetime of the fast recovery diode cell region; and forming a metal electrode layer on an upper surface of the fast recovery diode cell region, where the metal electrode layer is electrically connected to the copper electrode layer on the upper surface of the IGBT cell region.

Claim (Index 4):
The method according to  claim 1 , wherein the forming the copper electrode layer on the upper surface of the IGBT cell region comprises:\n forming a patterned mask layer on the upper surface of the IGBT cell region; forming a copper metal layer on the upper surface of the IGBT cell region; and removing the mask layer to form the copper electrode layer on the upper surface of the IGBT cell region.
