    摘要: A double gate germanium metal-oxide semiconductor field-effect transistor (MOSFET) includes a germanium fin, a first gate formed adjacent a first side of the germanium fin, and a second gate formed adjacent a second side of the germanium fin opposite the first side. A triple gate MOSFET includes a germanium fin, a first gate formed adjacent a first side of the germanium fin, a second gate formed adjacent a second side of the germanium fin opposite the first side, and a top gate formed on top of the germanium fin. An all-around gate MOSFET includes a germanium fin, a first sidewall gate structure formed adjacent a first side of the germanium fin, a second sidewall gate structure formed adjacent a second side of the germanium fin, and additional gate structures formed on and around the germanium fin.

    摘要: A method of fabricating an integrated circuit with ultra-shallow source/drain junctions utilizes a dummy or sacrificial gate structure. Dopants are provided through the openings associated with sacrificial spacers to form the source and drain extensions. The openings can be filled with spacers The process can be utilized for P-channel or N-channel metal oxide field semiconductor effect transistors (MOSFETS).

    摘要: A double-gate semiconductor device includes a substrate, an insulating layer, a fin, source and drain regions and a gate. The insulating layer is formed on the substrate and the fin is formed on the insulating layer. The source region is formed on the insulating layer adjacent a first side of the fin and the drain region is formed on the second side of the fin opposite the first side. The source and drain regions have a greater thickness than the fin in the channel region of the semiconductor device.

    摘要: A method of forming a gate in a FinFET device includes forming a fin on an insulating layer, forming source/drain regions and forming a gate oxide on the fin. The method also includes depositing a gate material over the insulating layer and the fin, depositing a barrier layer over the gate material and depositing a bottom anti-reflective coating (BARC) layer over the barrier layer. The method further includes forming a gate mask over the BARC layer, etching the BARC layer, where the etching terminates on the barrier layer, and etching the gate material to form the gate.
