Abstract:
820A/750V S3+ IGBT module implementing new IGBT and diode is presented. The Recessed-Emitter-Trench (RET) and Recessed-Dummy-Trench (RDT) fine pattern technology are used in the proposed IGBT, which shrink the mesa width to sub-micron without much reliance on special processes, and subsequently strongly improved VCE(ON) – EOFF relationship. For the diode, the Carrier-Profile-Control (CPC) technology and thin wafer technology are performed to obtain improved VF – EREC relationship and significantly reduced oscillation. As a result, the total loss of 820A/750V S3+ module is decreased by 29.6% when compared to the last generation product. Furthermore, the robust SOA performance and 175 ºC Tjmax are realized.
