    摘要: A semiconductor device includes a fin, a source region formed adjacent the fin and having a height greater than that of the fin, and a drain region formed adjacent the a second side of the fin and having a height greater than that of the fin. A metal gate region is formed at a top surface and at least one side surface of the fin. A width of the source and drain region may be greater than that of the fin. The semiconductor device may exhibit a reduced series resistance and an improved transistor drive current.

    摘要: A method of manufacturing an integrated circuit having a gate structure above a substrate that includes germanium utilizes at least one layer as a seal. The layer advantageously can prevent back sputtering and outdiffusion. A transistor can be formed in the substrate by doping through the layer. Another layer can be provided below the first layer. Layers of silicon dioxide, silicon carbide, silicon nitride, titanium, titanium nitride, titanium/titanium nitride, tantalum nitride, and silicon carbide can be used.

    摘要: A method of forming a fin field effect transistor includes forming a fin and forming a source region adjacent a first end of the fin and a drain region adjacent a second end of the fin. The method further includes forming a dummy gate over the fin and forming a dielectric layer around the dummy gate. The method also includes removing the dummy gate to form a trench in the dielectric layer and forming a metal gate in the trench.

    摘要: A method facilitates the formation of a stacked fin structure for a semiconductor device that includes a substrate. The method includes forming one or more oxide layers on the substrate and forming one or more amorphous silicon layers interspersed with the one or more oxide layers. The method further includes etching the one or more oxide layers and the one or more amorphous silicon layers to form a stacked fin structure and performing a metal-induced crystallization operation to convert the one or more amorphous silicon layers to one or more crystalline silicon layers.

    摘要: A fin field effect transistor includes a fin, a source region, a drain region, a first gate electrode and a second gate electrode. The fin includes a channel. The source region is formed adjacent a first end of the fin and the drain region is formed adjacent a second end of the fin. The first gate electrode includes a first layer of metal material formed adjacent the fin. The second gate electrode includes a second layer of metal material formed adjacent the first layer. The first layer of metal material has a different work function than the second layer of metal material. The second layer of metal material selectively diffuses into the first layer of metal material via metal interdiffusion.

    摘要: A strained silicon MOSFET utilizes a strained silicon layer formed on a silicon geranium layer. Strained silicon and silicon germanium are removed at opposing sides of the gate and are replaced by silicon regions. Deep source and drain regions are implanted in the silicon regions, and the depth of the deep source and drain regions does not extend beyond the depth of the silicon regions. By forming the deep source and drain regions in the silicon regions, detrimental effects of the higher dielectric constant and lower band gap of silicon geranium are reduced.
