    摘要: A method for making a dual silicide or germanide semiconductor comprises steps of providing a semiconductor substrate, forming a gate, forming source/drain regions, forming a first silicide, reducing spacers thickness and forming a second silicide. Forming a gate comprises forming an insulating layer over the semiconductor substrate, and forming the gate over the insulating layer. Forming source/drain regions comprises forming lightly doped source/drain regions in the semiconductor substrate adjacent to the insulating layer, forming spacers adjacent to the gate and over part of the lightly doped source/drain regions, and forming heavily doped source/drain regions in the semiconductor substrate. The first silicide is formed on an exposed surface of lightly and heavily doped source/drain regions. The second silicide is formed on an exposed surface of lightly doped source/drain regions. A first germanide and second germanide may replace the first silicide and the second silicide.

    摘要: A method for manufacturing a metal gate includes providing a substrate including a gate electrode located on the substrate. A plurality of layers is formed, including a first layer located on the substrate and the gate electrode and a second layer adjacent the first layer. The layers are etched to form a plurality of adjacent spacers, including a first spacer located on the substrate and adjacent the gate electrode and a second spacer adjacent the first spacer. The first spacer is then etched and a metal layer is formed on the device immediately adjacent to the gate electrode. The metal layer is then reacted with the gate electrode to form a metal gate.

    摘要: Nano-wires, preferably of less than 20 nm diameter, can be formed with minimized risk of narrowing and breaking that results from silicon atom migration during an annealing process step. This is accomplished by masking portion of the active layer where silicon atomer would otherwise agglomerate with a material such as silicon dioxide, silicon nitride, or other dielectric that eliminates or substantially reduces the silicon atom migration. Nano-wires, nanotubes, nano-rods, and other features can be formed and can optionally be incorporated into devices, such as by use as a channel region in a transistor device.
