摘要： A double-semiconductor device includes a substrate, an insulating layer, a fin and a gate. The insulating layer is formed on the substrate and the fin is formed on the insulating layer. The fin has a number of side surfaces, a top surface and a bottom surface. The gate is formed on the insulating layer and surrounds the top surface, bottom surface and the side surfaces of the fin in the channel region of the semiconductor device. Surrounding the fin with gate material results in an increased total channel width and more flexible device adjustment margins.

摘要： A method for forming a metal-oxide semiconductor field-effect transistor (MOSFET) includes patterning a fin area, a source region, and a drain region on a substrate, forming a fin in the fin area, and forming a mask in the fin area. The method further includes etching the mask to expose a channel area of the MOSFET, etching the fin to thin a width of the fin in the channel area, forming a gate over the fin, and forming contacts to the gate, the source region, and the drain region.

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.
