摘要： A method to achieve multiple threshold voltage (Vt) devices on the same semiconductor chip is disclosed. The method provides different threshold voltage devices using threshold voltage adjusting materials and a subsequent drive in anneal instead of directly doping the channel. As such, the method of the present disclosure avoids short channel penalties. Additionally, no ground plane/back gates are utilized in the present application thereby the method of the present disclosure can be easily integrated into current complementary metal oxide semiconductor (CMOS) processing technology.

摘要： A common cut mask is employed to define a gate pattern and a local interconnect pattern so that local interconnect structures and gate structures are formed with zero overlay variation relative to one another. A local interconnect structure may be laterally spaced from a gate structure in a first horizontal direction, and contact another gate structure in a second horizontal direction that is different from the first horizontal direction. Further, a gate structure may be formed to be collinear with a local interconnect structure that adjoins the gate structure. The local interconnect structures and the gate structures are formed by a common damascene processing step so that the top surfaces of the gate structures and the local interconnect structures are coplanar with each other.

摘要： A method of forming a semiconductor device is provided, in which the dopant for the source and drain regions is introduced from a doped dielectric layer. In one example, a gate structure is formed on a semiconductor layer of an SOI substrate, in which the thickness of the semiconductor layer is less than 10 nm. A doped dielectric layer is formed over at least the portion of the semiconductor layer that is adjacent to the gate structure. The dopant from the doped dielectric layer is driven into the portion of the semiconductor layer that is adjacent to the gate structure. The dopant diffused into the semiconductor provides source and drain extension regions.

摘要： A method includes providing a silicon-on-insulator wafer (e.g., an ETSOI wafer); forming a sacrificial gate structure that overlies a sacrificial insulator layer; forming raised source/drains adjacent to the sacrificial gate structure; depositing a layer that covers the raised source/drains and that surrounds the sacrificial gate structure; and removing the sacrificial gate structure leaving an opening that extends to the sacrificial insulator layer. The method further includes widening the opening so as to expose some of the raised source/drains, removing the sacrificial insulator layer and forming a spacer layer on sidewalls of the opening, the spacer layer covering only an upper portion of the exposed raised source/drains, and depositing a layer of gate dielectric material within the opening. A gate conductor is deposited within the opening.
