    摘要: A method of fabricating a circuit comprising an nMOSFET includes providing a substrate, depositing a strain-inducing material comprising germanium over the substrate, and integrating a pMOSFET on the substrate, the pMOSFET comprising a strained channel having a surface roughness of less than 1 nm. The strain-inducing material is proximate to and in contact with the pMOSFET channel, the strain in the pMOSFET channel is induced by the strain-inducing material, and a source and a drain of the pMOSFET are at least partially formed in the strain-inducing material.

    摘要: A semiconductor-based device includes a channel layer, which includes a distal layer and a proximal layer in contact with the distal layer. The distal layer supports at least a portion of hole conduction for at least one p-channel component, and the proximal layer supports at least a portion of electron conduction for at least one n-channel component. The proximal layer has a thickness that permits a hole wave function to effectively extend from the proximal layer into the distal layer to facilitate hole conduction by the distal layer. A method for fabricating a semiconductor-based device includes providing a distal portion of a channel layer and providing a proximal portion of the channel layer.
