    摘要: A semiconductor structure is provided which includes a first semiconductor device in a first active semiconductor region and a second semiconductor device in a second active semiconductor region. A first dielectric liner overlies the first semiconductor device and a second dielectric liner overlies the second semiconductor device, with the second dielectric liner overlapping the first dielectric liner at an overlap region. The second dielectric liner has a first portion having a first thickness contacting an apex of the second gate conductor and a second portion extending from peripheral edges of the second gate conductor which has a second thickness substantially greater than the first thickness. A first conductive via contacts at least one of the first or second gate conductors and the conductive via extends through the first and second dielectric liners at the overlap region. A second conductive via may contact at least one of a source region or a drain region of the second semiconductor device.

    摘要: A method forms a gate conductor over a substrate, and simultaneously forms spacers on sides of the gate conductor and a gate cap on the top of the gate conductor. Isolation regions are formed in the substrate and the method implants an impurity into exposed regions of the substrate not protected by the gate conductor and the spacers to form source and drain regions. The method deposits a mask over the gate conductor, the spacers, and the source and drain regions. The mask is recessed to a level below a top of the gate conductor but above the source and drain regions, such that the spacers are exposed and the source and drain regions are protected by the mask. With the mask in place, the method then safely removes the spacers and the gate cap, without damaging the source/drain regions or the isolation regions (which are protected by the mask). Next, the method removes the mask and then forms silicide regions on the gate conductor and the source and drain regions.

    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.
