  • Patent number: 9224814
    Abstract: The present disclosure relates to a method of forming a transistor device having a carbon implantation region that provides for a low variation of voltage threshold, and an associated apparatus. The method is performed by forming a well region within a semiconductor substrate. The semiconductor substrate is selectively etched to form a recess within the well region. After formation of the recess, a carbon implantation is selectively performed to form a carbon implantation region within the semiconductor substrate at a position underlying the recess. An epitaxial growth is then performed to form one or more epitaxial layers within the recess at a position overlying the carbon implantation region. Source and drain regions are subsequently formed within the semiconductor substrate such that a channel region, comprising the one or more epitaxial layers, separates the source/drains from one another.

  • Publication number: 20150333149
    Abstract: A semiconductor arrangement and method of formation are provided herein. A semiconductor arrangement includes a metal connect in contact with a first active region and a second active region, and over a shallow trench isolation region located between the first active region and a second active region. A method of forming the semiconductor arrangement includes recessing the metal connect over the STI region to form a recessed portion of the metal connect. Forming the recessed portion of the metal connect in contact with the first active region and the second active region mitigates RC coupling, such that a first gate is formed closer to a second gate, thus reducing a size of a chip on which the recessed portion is located.
