  • Patent number: 8766376
    Abstract: An embodiment is a method for forming a static random access memory (SRAM) cell. The method comprises forming transistors on a semiconductor substrate and forming a first linear intra-cell connection and a second linear intra-cell connection. Longitudinal axes of the active areas of the transistors are parallel. A first pull-down transistor and a first pull-up transistor share a first common gate structure, and a second pull-down transistor and a second pull-up transistor share a second common gate structure. The first linear intra-cell connection electrically couples active areas of the first pull-down transistor and the first pull-up transistor to the second common gate structure. The second linear intra-cell connection electrically couples active areas of the second pull-down transistor and the second pull-up transistor to the first common gate structure.

  • Patent number: 8461634
    Abstract: An integrated circuit device and method for manufacturing the same are disclosed. An exemplary device includes a semiconductor substrate having a substrate surface; a trench isolation structure disposed in the semiconductor substrate, the trench isolation structure having a trench isolation structure surface that is substantially planar to the substrate surface; and a gate feature disposed over the semiconductor substrate, wherein the gate feature includes a portion that extends from the substrate surface to a depth in the trench isolation structure, the portion being defined by a trench isolation structure sidewall and a semiconductor substrate sidewall, such that the portion tapers from a first width at the substrate surface to a second width at the depth, the first width being greater than the second width.
