Abstract: A method of patterning a semiconductor film is described. According to an embodiment of the present invention, a hard mask material is formed on a silicon film having a global crystal orientation wherein the semiconductor film has a first crystal plane and second crystal plane, wherein the first crystal plane is denser than the second crystal plane and wherein the hard mask is formed on the second crystal plane. Next, the hard mask and semiconductor film are patterned into a hard mask covered semiconductor structure. The hard mask covered semiconductor structured is then exposed to a wet etch process which has sufficient chemical strength to etch the second crystal plane but insufficient chemical strength to etch the first crystal plane.

Abstract: A method for fabricating a field-effect transistor with a gate completely wrapping around a channel region is described. Ion implantation is used to make the oxide beneath the channel region of the transistor more etchable, thereby allowing the oxide to be removed below the channel region. Atomic layer deposition is used to form a gate dielectric and a metal gate entirely around the channel region once the oxide is removed below the channel region.

Abstract: In a metal gate replacement process, strain may be selectively induced in the channels of NMOS and PMOS transistors. For example, a material having a higher coefficient of thermal expansion than the substrate may be used to form the gate electrodes of PMOS transistors. A material with a lower coefficient of thermal expansion than that of the substrate may be used to form the gate electrodes of NMOS transistors.

Abstract: A capacitor includes a substrate (110, 210), a first electrically insulating layer (120, 220) over the substrate, and a fin (130, 231) including a semiconducting material (135) over the first electrically insulating layer. A first electrically conducting layer (140, 810) is located over the first electrically insulating layer and adjacent to the fin. A second electrically insulating layer (150, 910) is located adjacent to the first electrically conducting layer, and a second electrically conducting layer (160, 1010) is located adjacent to the second electrically insulating layer. The first and second electrically conducting layers together with the second electrically insulating layer form a metal-insulator-metal stack that greatly increases the capacitance area of the capacitor. In one embodiment the capacitor is formed using what may be referred to as a removable metal gate (RMG) approach.
