    摘要: A method for fabricating MOS transistor includes the steps of: overlapping a second stress layer on an etching stop layer and a first stress layer at a boundary region of the substrate; forming a dielectric layer on the first stress layer and the second stress layer; performing a first etching process to partially remove the dielectric layer for exposing a portion of the second stress layer at the boundary region; performing a second etching process to partially remove the exposed portion of the second stress layer for exposing the etching stop layer; performing a third etching process to partially remove the exposed portion of the etching stop layer for exposing the first stress layer at the boundary region; and performing a fourth etching process partially remove the exposed portion of the first stress layer.

    摘要: A semiconductor process includes the following steps. A first structure and a second structure are formed on a substrate. An oxide layer is entirely formed to cover the first structure and the second structure. A nitride layer is formed to entirely cover the oxide layer. A dry etching process is performed to remove a part of the nitride layer on the first structure. A wet etching process is performed to entirely remove the nitride layer and the oxide layer on the first structure and the second structure.
