    摘要: Techniques are disclosed for enabling multi-sided condensation of semiconductor fins. The techniques can be employed, for instance, in fabricating fin-based transistors. In one example case, a strain layer is provided on a bulk substrate. The strain layer is associated with a critical thickness that is dependent on a component of the strain layer, and the strain layer has a thickness lower than or equal to the critical thickness. A fin is formed in the substrate and strain layer, such that the fin includes a substrate portion and a strain layer portion. The fin is oxidized to condense the strain layer portion of the fin, so that a concentration of the component in the strain layer changes from a pre-condensation concentration to a higher post-condensation concentration, thereby causing the critical thickness to be exceeded.

    摘要: A trigate device having an extended metal gate electrode comprises a semiconductor body having a top surface and opposing sidewalls formed on a substrate, an isolation layer formed on the substrate and around the semiconductor body, wherein a portion of the semiconductor body remains exposed above the isolation layer, and a gate stack formed on the top surface and opposing sidewalls of the semiconductor body, wherein the gate stack extends a depth into the isolation layer, thereby causing a bottom surface of the gate stack to be below a top surface of the isolation layer.
