Abstract: After formation of a gate cavity straddling at least one semiconductor material portion, a gate dielectric layer and at least one work function material layer is formed over the gate dielectric layer. The at least one work function material layer and the gate dielectric layer are patterned such that remaining portions of the at least one work function material layer are present only in proximity to the at least one semiconductor material portion. A conductive material having a greater conductivity than the at least one work function material layer is deposited in remaining portions of the gate cavity. The conductive material portion within a replacement gate structure has the full width of the replacement gate structure in regions from which the at least one work function material layer and the gate dielectric layer are removed.

Abstract: Methods and structures for capacitively isolating a heat shield from a handle wafer of a silicon-on-insulator substrate. A contact plug is located in a trench extending through a trench isolation region in a device layer of the silicon-on-insulator substrate and at least partially through a buried insulator layer of the silicon-on-insulator substrate. The heat shield is located in an interconnect structure, which also includes a wire coupling the heat shield with the contact plug. An isolation structure is positioned between the contact plug and a portion of the handle wafer. The isolation structure provides the capacitive isolation.

Abstract: A buried conductive layer is formed underneath a buried insulator layer of a semiconductor-on-insulator (SOI) substrate. A deep isolation trench laterally surrounding a portion of the buried conductive layer is formed, and is filled with at least a dielectric liner to form a deep capacitor trench isolation structure. Contact via structures are formed through the buried insulator layer and a top semiconductor layer and onto the portion of the buried conductive layer, which constitutes a buried conductive conduit. The deep capacitor trench isolation structure may be formed concurrently with at least one deep trench capacitor. A patterned portion of the top semiconductor layer may be employed as an additional conductive conduit for signal transmission. Further, the deep capacitor trench isolation structure may include a conductive portion, which can be electrically biased to control the impedance of the signal path including the buried conductive conduit.

Abstract: A gate contact with reduced contact resistance is provided by increasing contact area between the gate contact and a gate conductive portion of a gate structure. The gate contact forms a direct contact with a topmost surface and at least portions of outermost sidewalls of a portion of the gate conductive portion, thus increasing the contact area between the gate contact and the gate structure. The gate contact area of the present application can be further increased by completely surrounding a portion of the gate conductive portion of the gate structure with the gate contact.
