    Abstract: Methods of manufacturing are provided. In one aspect, a method of manufacturing is provided that includes forming first and second gate stacks on a substrate and forming an insulating layer on the substrate. The insulating layer has portions adjacent to the first stack and portions adjacent to the second gate stack. A first pair of insulating structures is formed adjacent to the first gate stack and a second pair of insulating structures is formed adjacent to the second gate stack. The first pair of insulating structures is removed. The portions of the insulating layer adjacent to the first gate stack are thickened while the second pair of insulating structures prevents thickening of the portions of the insulating film adjacent to the second gate stack. Differential insulating layer thickness for different gate devices is permitted to enable reduction in leakage currents for selected devices without harming speed performance for others.

    Abstract: The present invention is directed toward a method for independently doping the gate and the source-drain regions of a semiconductor device. The method is initiated by the provision. of a substrate having isolation regions and a thin insulating layer. Over the substrate is formed a polysilicon layer which is doped with a first type of dopant at a first doping level. Over the polysilicon layer is formed a conducting layer of material that can withstand temperatures of 1000° C., and over the conducting layer is formed a blocking layer. The polysilicon layer, the conducting layer and the blocking layer are etched to form a gate stack. Source-drain regions are subsequently doped with a second type of dopant at a second doping level. Source-drain regions are activated in a 1000° C. heat cycle, and, subsequently, TiSi2 is formed on the source-drain regions. Contacts are then formed. The blocking layer on the gate stack need not be removed, which aids in minimizing substrate damage and in prevention of shorting a source-drain contact region to the substrate.

    Abstract: A method of fabricating a semiconductor device is provided. The method forms a fin arrangement on a semiconductor substrate, the fin arrangement comprising one or more semiconductor fin structures. The method continues by forming a gate arrangement overlying the fin arrangement, where the gate arrangement includes one or more adjacent gate structures. The method proceeds by forming an outer spacer around sidewalls of each gate structure. The fin arrangement is then selectively etched, using the gate structure and the outer spacer(s) as an etch mask, resulting in one or more semiconductor fin sections underlying the gate structure(s). The method continues by forming a stress/strain inducing material adjacent sidewalls of the one or more semiconductor fin sections.
