摘要:
A method for fabricating a trench in a semiconductor device includes forming a mask pattern over a substrate, and etching the substrate to form a trench with a vertical profile, the etching performed at an etching rate of approximately 40 A/sec or less using an etching gas including a gas generating polymers
