Title: Insulating gate type bipolar transistor
Inventor: IWAMURO NORIYUKI
IPC: H01L21/336
Filed: 1991-10-24
Abstract: PURPOSE:To avoid the latch up phenomenon by shortening the life time of a gate pad lower part. CONSTITUTION:A p<+> channel formation layer 4 is not formed on the n<-> layer 3 beneath a gate pad part 12, and the minority carriers accumulated in that part during ON time flow out of a source terminal through adjacent p<+> channel formation layer 4 during OFF time under the condition where an in ductive load is connected. Accordingly, multiple carriers concentrically flow into the p<+> carrier formation layer 4 in this part thereby causing latch-up phenomenon. Accordingly, the minority carrier life time is shortened only on the part beneath a gate pad part 12 of the p<+> channel formation layer 4 where minority carriers are accumulated, by locally irradiating step with an electron beam or protons. Resultantly, the carrier amount concentrated in the p<+> channel formation layer 4 adjacent to the lower part of the gate pad part 12 can be reduced. Through these procedures, the latch-up phenomenon can be avoided.
