The planar IGCT concept has been verified experimentally with 4.5kV devices fabricated on 4-inch Si wafers. Afterwards, the electrical characteristics of the planar IGCT were compared with that of the conventional (with trench or mesa gate) IGCT. Both the planar and the conventional IGCTs are fabricated with corrugated p-base referred to as High Power Technology (HPT) design. In addition, mixed-mode TCAD device simulations have been performed to verify the turn-off failure mechanism and to analyze the electro-thermal performance of the planar IGCT in reference to that of the conventional IGCT. | URI: | https://hdl.handle.net/20.500.14279/33368 | ISBN: | [9781728148366] | ISSN: | 10636854 | DOI: | 10.1109/ISPSD46842.2020.9170102 | Rights: | Attribution-NonCommercial-NoDerivatives 4.0 International | Type: | Conference Papers | Affiliation : | Abb Power Grids University of Nottingham University of Cambridge |
