摘要:
An electronic device includes a conductive channel defining a crystal structure and having a length and a thickness tC; and a dielectric film of thickness tg in contact with a surface of the channel. Further, the film comprises a material that exerts one of a compressive or a tensile force on the contacted surface of the channel such that electrical mobility of the charge carriers (electrons or holes) along the channel length is increased due to the compressive or tensile force in dependence on alignment of the channel length relative to the crystal structure. Embodiments are given for chips with both hole and electron mobility increased in different transistors, and a method for making such a transistor or chip.

A system and method for modeling a semiconductor transistor device structure having a conductive line feature of a designed length connected to a gate of a transistor device in a circuit to be modeled, the transistor including an active device (RX) area over which the gate is formed and over which the conductive line feature extends. The method includes providing an analytical model representation including a function for modeling a lithographic flare effect impacting the active device area width; and, from the modeling function, relating an effective change in active device area width (deltaW adder) as a function of a distance from a defined edge of the RX area. Then, transistor model parameter values in a transistor compact model for the device are updated to include deltaW adder values to be added to a built-in deltaW value. A netlist used in a simulation includes the deltaW adder values to more accurately describe the characteristics of the transistor device being modeled including modeling of lithographic corner rounding effect on transistor device parametrics.

A semiconductor structure and method for forming dielectric spacers and epitaxial layers for a complementary metal-oxide-semiconductor field effect transistor (CMOS transistor) are disclosed. Specifically, the structure and method involves forming dielectric spacers that are disposed in trenches and are adjacent to the silicon substrate, which minimizes leakage current. Furthermore, epitaxial layers are deposited to form source and drain regions, wherein the source region and drain regions are spaced at a distance from each other. The epitaxial layers are disposed adjacent to the dielectric spacers and the transistor body regions (i.e., portion of substrate below the gates), which can minimize transistor junction capacitance. Minimizing transistor junction capacitance can enhance the switching speed of the CMOS transistor. Accordingly, the application of dielectric spacers and epitaxial layers to minimize leakage current and transistor junction capacitance in CMOS transistors can enhance the utility and performance of the CMOS transistors in low power applications.

A semiconductor device and method of manufacturing a semiconductor device. The semiconductor device includes channels for a pFET and an nFET. A SiGe layer is selectively grown in the source and drain regions of the pFET channel and a Si:C layer is selectively grown in source and drain regions of the nFET channel. The SiGe and Si:C layer match a lattice network of the underlying Si layer to create a stress component. In one implementation, this causes a compressive component in the pFET channel and a tensile component in the nFET channel.

The method of manufacturing includes forming shallow trench isolation (STI) in a substrate and providing a first material and a second material on the substrate. The first material and the second material are mixed into the substrate by a thermal anneal process to form a first island and second island at an nFET region and a pFET region, respectively. A layer of different material is formed on the first island and the second island. The STI relaxes and facilitates the relaxation of the first island and the second island. The first material may be deposited or grown Ge material and the second material may deposited or grown Si:C or C. A strained Si layer is formed on at least one of the first island and the second island.

摘要:
A semiconductor nanowire having two semiconductor pads on both ends is suspended over a substrate. Stress-generating liner portions are formed over the two semiconductor pads, while a middle portion of the semiconductor nanowire is exposed. A gate dielectric and a gate electrode are formed over the middle portion of the semiconductor nanowire while the semiconductor nanowire is under longitudinal stress due to the stress-generating liner portions. The middle portion of the semiconductor nanowire is under a built-in inherent longitudinal stress after removal of the stress-generating liners because the formation of the gate dielectric and the gate electrode locks in the strained state of the semiconductor nanowire. Source and drain regions are formed in the semiconductor pads to provide a semiconductor nanowire transistor. A middle-of-line (MOL) dielectric layer may be formed directly on the source and drain pads.
