WebSide gate HiGT has a side-wall gate, and the opposite side of channel region for side-wall gate is covered by a thick oxide layer to reduce Miller capacitance (Cres). In addition, side gate HiGT has no floating p-layer, which causes the excess Vge overshoot. The proposed side gate HiGT has 75% smaller Cres than the conventional trench gate IGBT. WebFor the 90-nm node, with thinner gate oxide and silicide, this degradation will increase very much, thus requiring a drastic decrease of capacitor thermal budget. Ideally, in reducing capacitor formation temperature, we should aim around the maximum temperature in the back-end-of-line, which is around 400 °C.
