    摘要: A structure includes a substrate; a transistor disposed over the substrate, the transistor comprising a fin comprised of Silicon that is implanted with Carbon; and a gate dielectric layer and gate metal layer overlying a portion of the fin that defines a channel of the transistor. In the structure a concentration of Carbon within the fin is selected to establish a desired voltage threshold of the transistor. Methods to fabricate a FinFET transistor are also disclosed. Also disclosed is a planar transistor having a Carbon-implanted well where the concentration of the Carbon within the well is selected to establish a desired voltage threshold of the transistor.
