    摘要: A method for forming a resist protect layer on a semiconductor substrate includes the following steps. An isolation structure is formed on the semiconductor substrate. An original nitride layer having a substantial etch selectivity to the isolation structure is formed over the semiconductor substrate. A photoresist mask is formed for partially covering the original nitride layer. A wet etching is performed to remove the original nitride layer uncovered by the photoresist mask in such a way without causing substantial damage to the isolation structure. As such, the original nitride layer covered by the photoresist mask constitutes the resist protect layer.

    摘要: An integrated advanced method for forming a semiconductor device utilizes a sacrificial stress layer as part of a film stack that enables spatially selective silicide formation in the device. The low-resistance portion of the device to be silicided includes NMOS transistors and PMOS transistors. The stressed film may be a tensile or compressive nitride film. An annealing process is carried out prior to the silicide formation process. During the annealing process, the stressed nitride film preferentially remains over either the NMOS transistors or PMOS transistors, but not both, to optimize device performance. A tensile nitride film remains over the NMOS transistors but not the PMOS transistors while a compressive nitride film remains over the PMOS transistors but not the NMOS transistors, during anneal.
