    Abstract: A FinFET device includes a substrate, a gate structure positioned above the substrate, and sidewall spacers positioned adjacent to the gate structure. An epi semiconductor material is positioned in source and drain regions of the FinFET device and laterally outside of the sidewall spacers. A fin extends laterally under the gate structure and the sidewall spacers in a gate length direction of the FinFET device, wherein the end surfaces of the fin abut and engage the epi semiconductor material. A stressed material is positioned in a channel cavity located below the fin, above the substrate, and laterally between the epi semiconductor material, the stressed material having a top surface that abuts and engages a bottom surface of the fin, a bottom surface that abuts and engages the substrate, and end surfaces that abut and engage the epi semiconductor material.

    Abstract: An integrated circuit transistor is formed on a substrate. A trench in the substrate is at least partially filled with a metal material to form a source (or drain) contact buried in the substrate. The substrate further includes a source (or drain) region in the substrate which is in electrical connection with the source (or drain) contact. The substrate further includes a channel region adjacent to the source (or drain) region. A gate dielectric is provided on top of the channel region and a gate electrode is provided on top of the gate dielectric. The substrate may be of the silicon on insulator (SOI) or bulk type. The buried source (or drain) contact makes electrical connection to a side of the source (or drain) region using a junction provided at a same level of the substrate as the source (or drain) and channel regions.

    Abstract: Integrated circuits and methods for fabricating integrated circuits are provided. In one example, an integrated circuit includes a semiconductor substrate. A first fin and a second fin are adjacent to each other extending from the semiconductor substrate. The first fin has a first upper section and the second fin has a second upper section. A first epi-portion overlies the first upper section and a second epi-portion overlies the second upper section. A first silicide layer overlies the first epi-portion and a second silicide layer overlies the second epi-portion. The first and second silicide layers are spaced apart from each other to define a lateral gap. A dielectric spacer is formed of a dielectric material and spans the lateral gap. A contact-forming material overlies the dielectric spacer and portions of the first and second silicide layers that are laterally above the dielectric spacer.
