Abstract This paper proposes a novel collector trench insulated gate bipolar transistor (CT-IGBT) with an electron extraction channel formed on the collector side to enhance the electron extraction effect, in which a low doped n-type layer is introduced to increase hole injection efficiency at the collector side. TCAD simulation indicates that the proposed IGBT structure offers a turn-off fall time 49% lower and avalanche energy 32% higher than a conventional field-stop IGBT (FS-IGBT). Therefore, the proposed IGBT is attractive for high-speed and large-power electronic converters.
