    摘要: A method of manufacturing a metal-oxide-semiconductor (MOS) transistor device is disclosed. A gate dielectric layer is formed on an active area of a substrate. A gate electrode is patterned on the gate dielectric layer. The gate electrode has vertical sidewalls and a top surface. A liner is formed on the vertical sidewalls of the gate electrode. A nitride spacer is formed on the liner. An ion implanted is performed to form a source/drain region. After salicide process, an STI region that isolates the active area is recessed, thereby forming a step height at interface between the active area and the STI region. The nitride spacer is removed. A nitride cap layer that borders the liner is deposited. The nitride cap layer has a specific stress status.

    摘要: A method of improving photoresist adhesion in a reworked device, including the following steps. A semiconductor structure having an upper exposed metal layer is provided. An ARC layer is formed over the upper exposed metal layer. The ARC layer having an upper surface. A first photoresist layer is formed upon the ARC layer. The first photoresist layer is removed by a rework process. The ARC layer upper surface is roughened to form a roughened ARC layer upper surface. A second photoresist layer is formed upon the roughened ARC layer upper surface whereby adhesion of the second photoresist layer to the ARC layer is improved.
