    摘要: A pattern in a surface is defined by providing on the surface a hard mask material; depositing an anti-reflective coating on the hard mask material; applying a photoresist layer on the anti-reflective coating; patterning the photoresist layer, anti-reflective layer and hard mask material; and removing the remaining portions of the photoresist layer and anti-reflective layer; and then patterning the substrate using the hard mask as the mask. Also provided is a structure for defining a pattern in a surface which comprises a surface having a hard mask material thereon; an anti-reflective coating located on the hard mask material; and a photoresist located on the anti-reflective coating. Also provided is an etchant composition for removing the hard mask material which comprises an aqueous composition of HF and chlorine.

    摘要: An etch resistant liner covering sidewalls of a transistor gate stack and along a portion of the substrate at a base of the transistor gate stack. The liner prevents silicide formation on the sidewalls of the gate stack, which may produce electrical shorting, and determines the location of silicide formation within source and drain regions within the substrate at the base of the transistor gate stack. The liner also covers a resistor gate stack preventing silicide formation within or adjacent to the resistor gate stack.

    摘要: A method for providing a dual stress memory technique in a semiconductor device including an nFET and a PFET and a related structure are disclosed. One embodiment of the method includes forming a tensile stress layer over the nFET and a compressive stress layer over the pFET, annealing to memorize stress in the semiconductor device and removing the stress layers. The compressive stress layer may include a high stress silicon nitride deposited using a high density plasma (HDP) deposition method. The annealing step may include using a temperature of approximately 400-1200° C. The high stress compressive silicon nitride and/or the anneal temperatures ensure that the compressive stress memorization is retained in the pFET.
