Investigation of Deep Trench Process for Trench-gate IGBT

Deep trench plasma etch process which is suitable for trench-gate IGBT has been developed based on Lam 4420 reactive ion etching (RIE) tool and Cl2. An undercut-free 6 μm-deep trench with round bottom corners and around 3°sidewall slope is obtained by carefully adjusting additive gases like HBr, O2...
