Abstract: The present disclosure relates to semiconductor structures and, more particularly, to stacked gate transistors and methods of manufacture.

Abstract: A dielectric fill layer within source/drain metallization trenches limits the depth of an inlaid metallization layer over isolation regions of a semiconductor device. The modified geometry decreases parasitic capacitance as well as the propensity for electrical short circuits between the source/drain metallization and adjacent conductive structures, which improves device reliability and performance.

Abstract: A dummy gate structure straddling at least one semiconductor fin is formed on a substrate. Active semiconductor regions and raised active semiconductor regions may be formed. A planarization dielectric layer is formed over the at least one semiconductor fin, and the dummy gate structure is removed to provide a gate cavity. Electrical dopants in the channel region can be removed by outgassing during an anneal, thereby lowering the concentration of the electrical dopants in the channel region. Alternately or additionally, carbon can be implanted into the channel region to deactivate remaining electrical dopants in the channel region. The threshold voltage of the field effect transistor can be effectively controlled by the reduction of active electrical dopants in the channel region. A replacement gate electrode can be subsequently formed in the gate cavity.

Abstract: A method of making a semiconductor device includes disposing a mask on a substrate; etching the mask to form an opening in the mask; etching a trench in the substrate beneath the opening in the mask; and implanting a dopant in an area of the substrate beneath the opening of the mask, the dopant capable of gettering mobile ions that can contaminate the substrate; wherein the dopant extends through the substrate from a sidewall of the trench and an endwall of the trench.

Abstract: A self-aligned active region block mask is used to pattern and define a plurality of semiconductor fins as well as attendant shallow trench isolation (STI) structures. The block mask, a portion of which comprises a patterned fin hard mask, permits decoupling of inner and outer fin etch processes, as well as independent optimization of inner fin and outer fin dielectric properties. The fin-forming method also forestalls the creation of isolated, free-standing fins, which decreases the likelihood of mechanical damage to the fins during processing.

Abstract: A fin cut process cuts semiconductor fins after forming sacrificial gate structures that overlie portions of the fins. Selected gate structures are removed to form openings and exposed portions of the fins within the openings are etched. An isolation dielectric layer is deposited into the openings and between end portions of the cut fins. The process enables a single sacrificial gate structure to define the spacing between two active regions on dissimilar electrical nets.
