    摘要: 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.

    摘要: By recessing a semiconductor layer, preferably by locally oxidizing the semiconductor layer, a stress-inducing material and/or a dopant species may be introduced into the thinned semiconductor layer in the vicinity of a gate electrode structure by means of a subsequent epitaxial growth process. In particular, the stress-inducing material formed adjacent to the gate electrode structure exerts compressive or tensile stress, depending on the type of material deposited, thereby also enhancing the mobility of the charge carriers in a channel region of the transistor element.

    摘要: An insulated gate semiconductor device (100) having reduced gate resistance and a method for manufacturing the semiconductor device (100). A gate structure (112) is formed on a major surface (104) of a semiconductor substrate (102). Successive nitride spacers (118, 128) are formed adjacent the sidewalls of the gate structure (112). The nitride spacers (118, 128) are etched and recessed using a single etch to expose the upper portions (115A, 117A) of the gate structure (112). Source (132) and drain (134) regions are formed in the semiconductor substrate (102). Silicide regions (140, 142, 144) are formed on the top surface (109) and the exposed upper portions (115A, 117A) of the gate structure (112) and the source region (132) and the drain region (134). Electrodes (150, 152, 154) are formed in contact with the silicide (140, 142, 144) of the respective gate structure (112), source region (132), and the drain region (134).

    摘要: Channel carrier mobility is increased by reducing gate/gate dielectric interface roughness, thereby reducing surface scattering. Embodiments include depositing a layer of silicon by selective epitaxy prior to gate oxide formation to provide a substantially atomically smooth surface resulting in a smoother interface between the gate polysilicon and silicon oxide after oxidation.

    摘要: A local oxidation of silicon (LOCOS) process directed to forming differential field oxide thickness on a single wafer with minimized process steps and optimized planarity. When patterning the masking layer, at least two window widths are formed in the masking layer, exposing the underlying substrate and pad oxide. When one of the window widths is sufficiently small, oxidation of the substrate will be inhibited causing reduced growth and thus a reduced field oxide thickness in that window as compared to other larger windows formed in the same masking layer, creating differential field oxide thicknesses in one growth step. To optimize planarity, prior to oxidation variable depth trenches are formed in alignment with the windows so that the resulting field oxide regions are substantially planar with the substantial surface.
