Integrated circuits with selectively stressed semiconductor-on-insulator (SOI) body contacts and methods for fabricating integrated circuits with selectively stressed SOI body contacts are provided. An exemplary method for fabricating an integrated circuit includes forming a channel region and a body contact overlying and/or in an SOI substrate. Further, the method includes selectively applying a first stress to the source/drain region in a longitudinal direction. Also, the method includes selectively applying a second stress to the body contact in a lateral direction perpendicular to the longitudinal direction.

A structure and method of reducing junction capacitance of a source/drain region in a transistor. A gate structure is formed over on a first conductive type substrate. We perform a doped depletion region implantation by implanting ions being the second conductive type to the substrate using the gate structure as a mask, to form a doped depletion region beneath and separated from the source/drain regions. The doped depletion regions have an impurity concentration and thickness so that the doped depletion regions are depleted due to a built-in potential creatable between the doped depletion regions and the substrate. The doped depletion region and substrate form depletion regions between the source/drain regions and the doped depletion region. We perform a S/D implant by implanting ions having a second conductivity type into the substrate to form S/D regions. The doped depletion region and depletion regions reduce the capacitance between the source/drain regions and the substrate.

A system is provided for forming a semiconductor device. Layers of gate dielectric material, gate material, and cap material are formed on a semiconductor substrate. The cap material and a portion of the gate material are processed to form a cap and a gate body portion. A wing on the gate body portion is formed from a remaining portion of the gate material. The gate dielectric material under a portion of the wing on the gate body portion is removed to form a gate dielectric. A lightly-doped source/drain region is formed in the semiconductor substrate using the gate body portion and the wing.

A structure and method for forming a carbon-containing layer in at least a portion of the end of range regions of implanted PAI and/or doped regions. The C-containing layer/region getters defects from the implanted PAI region or doped region. Example embodiments show a C-containing layer under at FET. Other example embodiments show an implanted C-containing regions implanted into the EOR region of implanted doped regions, such as pocket regions, S/D regions and SDE regions. Low temperature anneals can be used because the carbon-containing layer reduces defects.

The invention provides a new multilevel interconnect structure of air gaps in a layer of IMD. A first layer of dielectric is provided over a surface; the surface contains metal points of contact. Trenches are provided in this first layer of dielectric. The trenches are filled with a first layer of nitride or disposable solid and polished. A second layer of dielectric is deposited over the first layer of dielectric. Trenches are formed in the second layer of dielectric, a second layer of nitride or disposable solid is deposited over the second layer of dielectric. The layer of nitride or disposable solid is polished. A thin layer of oxide is deposited over the surface of the second layer of dielectric. The thin layer of oxide is masked and etched thereby creating openings in this thin layer of oxide, these openings align with the points of intersect of the trenches in the first layer of dielectric and in the second layer of dielectric. The nitride or removable solid is removed from the trenches. The openings in the thin layer of oxide are closed off leaving a network of trenches that are filled with air in the two layers of dielectric that now function as the Inter Level Dielectric.

A design, device, system and process for placing slots in active regions (e.g., metal areas). Embodiments of the present invention improve the planarization of metal areas (e.g., lines) and insulators by reducing depressions (e.g., dishing) in the metal areas by including symmetric or square slots inside selected wide metal lines, by adhering to a set of placement rules. Embodiments reduce dishing in copper dual damascene structures. Embodiments reduce data processing requirements for designing and arranging the layout of IC devices and the slots.

A process to form a FET using a replacement gate. An example feature is that the PMOS sacrificial gate is made narrower than the NMOS sacrificial gate. The PMOS gate is implanted preferably with Ge to increase the amount of poly sacrificial gate that is oxidized to form PMOS spacers. The spacers are used as masks for the LDD Implant. The space between the PLDD regions is preferably larger that the space between the NLDD regions because of the wider PMOS spacers. The PLDD tends to diffuse readily more than NLDD due to the dopant being small and light (i.e. Boron). The wider spacer between the PMOS regions improves device performance by improving the short channel effects for PMOS. In addition, the oxidization of the sacrificial gates allows trimming of sacrificial gates thus extending the limitation of lithography. Another feature of an embodiment is that a portion of the initial pad oxide is removed, thus reducing the amount of undercut created during the channel oxide strip for the dummy gate process. This would improve on the gate overlap capacitance for a T-gate transistor. In a second embodiment, two metal gates with different work functions are formed.

Method of forming wing gate transistor for integrated circuits

A MOSFET device structure formed on a silicon on insulator layer, and a process sequence employed to fabricate said MOSFET device structure, has been developed. The process features insulator filled, shallow trench isolation (STI) regions formed in specific locations of the MOSFET device structure for purposes of reducing the risk of parasitic transistor formation underlying a gate structure junction. After formation of either a 'T' shaped, or an 'H' shaped gate structure, body contact regions of a first conductivity type are formed adjacent to both an STI region and to a component of the gate structure. Formation of a source/drain region of a second conductivity type located on the opposite side of the same STI region, and the same gate structure component, is next performed. Unwanted parasitic transistor formation, which can occur underlying the gate structure via the body contact region and the source/drain region, is prevented by the presence of the separating STI region.
