摘要： Impurities are formed in the active region of a semiconductor substrate by diffusion from a gate electrode sidewall spacer. A gate electrode is formed on a semiconductor substrate with a gate dielectric layer therebetween. Sidewall spacers are formed on the side surfaces of the gate electrode. Dopant atoms are subsequently introduce to transform the spacers into solid dopant sources. Dopant atoms are diffused from the spacers into the semiconductor substrate to form first doped regions.

摘要： A process in accordance with the invention minimizes the number of heat steps to which an source-drain extension region is exposed, thus minimizing source-drain extension region diffusion and allowing more precise control of source-drain extension region thickness over conventional processes. In accordance with the invention, spacers are formed abutting the gate and then heavily doped source and drain regions are formed. The gate and source and drain regions are silicided. The spacers are subsequently removed and source-drain extension regions are then formed. In one embodiment of the invention, a laser doping process is used to form the source-drain extension regions.

摘要： Methods for fabricating semiconductor structures, such as fin structures of FinFET transistors, are provided. In one embodiment, a method comprises providing a semiconductor substrate and forming a plurality of mandrels overlying the semiconductor substrate. Each of the mandrels has sidewalls. L-shaped spacers are formed about the sidewalls of the mandrels. Each L-shaped spacer comprises a rectangular portion disposed at a base of a mandrel and an orthogonal portion extending from the rectangular portion. Each L-shaped spacer also has a spacer width. The orthogonal portions are removed from each of the L-shaped spacers leaving at least a portion of the rectangular portions. The semiconductor substrate is etched to form fin structures, each fin structure having a width substantially equal to the spacer width.

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.

A gate electrode overlies the gate insulator and defines a channel region in the silicon substrate underlying the gate electrode. A first silicon germanium region having a first thickness is embedded in the silicon substrate and contacts the channel region. A second silicon germanium region having a second thickness greater than the first thickness and spaced apart from the channel region is also embedded in the silicon substrate.

摘要： Methods and a structure are disclosed for providing stacking fault reduced epitaxially grown silicon for use in hybrid surface orientation structures. In one embodiment, a method includes depositing a silicon nitride liner over a silicon oxide liner in an opening, etching to remove the silicon oxide liner and silicon nitride liner on a lower surface of the opening, undercutting the silicon nitride liner adjacent to the lower surface, and epitaxially growing silicon in the opening. The silicon is substantially reduced of stacking faults because of the negative slope created by the undercut.

摘要： Integration schemes are presented which provide for decoupling the placement of deep source/drain (S/D) implants with respect to a selective epitaxial growth (SEG) raised S/D region, as well as decoupling silicide placement relative to a raised S/D feature. These integration schemes may be combined in multiple ways to permit independent control of the placement of these features for optimizing device performance. The methodology utilizes multiple spacers to decrease current crowding effects in devices due to proximity effects between LDD and deep S/D regions in reduced architecture devices.

摘要： A semiconductor device is provided with semiconducting sidewall spacers used in the formation of source/drain regions. The semiconducting sidewall spacers also reduce the possibility of suicide shorting through shallow source/drain junctions. Embodiments include doping the semiconducting sidewall spacers so that they serve as a source of impurities for forming source/drain extensions during activation annealing.
