    摘要: An ultra-large scale CMOS integrated circuit semiconductor device is processed after the formation of the gates and gate oxides by N-type dopant implantation to form N-type shallow source and drain extension junctions. Spacers are formed for N-type dopant implantation to form N-type deep source and drain junctions. A higher temperature rapid thermal anneal then optimizes the NMOS source and drain extension junctions and junctions, and the spacers are removed. A thin oxide spacer is used to displace P-type dopant implantation to P-type shallow source and drain extension junctions. A nitride spacer is then formed for P-type dopant implantation to form P-type deep source and drain junctions. A second lower temperature rapid thermal anneal then independently optimizes the PMOS source and drain junctions independently from the NMOS source and drain junctions.

    摘要: A double gate metal-oxide semiconductor field-effect transistor (MOSFET) includes a fin, a first gate and a second gate. The first gate is formed on top of the fin. The second gate surrounds the fin and the first gate. In another implementation, a triple gate MOSFET includes a fin, a first gate, a second gate, and a third gate. The first gate is formed on top of the fin. The second gate is formed adjacent the fin. The third gate is formed adjacent the fin and opposite the second gate.

    摘要: A method for doping fin structures in FinFET devices includes forming a first glass layer on the fin structure of a first area and a second area. The method further includes removing the first glass layer from the second area, forming a second glass layer on the fin structure of the first area and the second area, and annealing the first area and the second area to dope the fin structures.

    摘要: A non-volatile memory device includes a substrate, an insulating layer, a fin, an oxide layer, spacers and one or more control gates. The insulating layer is formed on the substrate and the fin is formed on the insulating layer. The oxide layer is formed on the fin and acts as a tunnel oxide for the memory device. The spacers are formed adjacent the side surfaces of the fin and the control gates are formed adjacent the spacers. The spacers act as floating gate electrodes for the non-volatile memory device.

    摘要: A method of manufacturing semiconductor fins for a semiconductor device may begin by providing a bulk semiconductor substrate. The method continues by growing a layer of first epitaxial semiconductor material on the bulk semiconductor substrate, and by growing a layer of second epitaxial semiconductor material on the layer of first epitaxial semiconductor material. The method then creates a fin pattern mask on the layer of second epitaxial semiconductor material. The fin pattern mask has features corresponding to a plurality of fins. Next, the method anisotropically etches the layer of second epitaxial semiconductor material, using the fin pattern mask as an etch mask, and using the layer of first epitaxial semiconductor material as an etch stop layer. This etching step results in a plurality of fins formed from the layer of second epitaxial semiconductor material.
