摘要： A 6F2 memory cell structure and a method of fabricating the same. The memory cell structure includes a plurality of memory cells located in a Si-containing substrate which are arranged in rows and columns. Each memory cell includes a double-gated vertical MOSFET having exposed gate conductor regions and two gates formed on opposing sidewalls of the MOSFETs. The memory cell structure also includes a plurality of wordlines overlaying the double-gated vertical MOSFETs and in contact with the exposed gate conductor regions, and a plurality of bitlines that are orthogonal to the wordlines. Trench isolation regions are located adjacent to the rows of memory cells. The memory cell structure also includes a plurality of punch through stop regions located in the Si-containing substrate and self-aligned to the wordlines and bitlines. A portion of the punch through stop regions overlap each other under the bitlines and each region serves to electrically isolate adjacent buried-strap regions from each other.

摘要： A method (and computer program) identify shapes and locations of transistor elements within a geometric circuit layout. The transistor elements include an active area, at least one gate conductor and other transistor elements. Also, the gate conductor has sides running in a first direction, and has a width dimension running in a second direction perpendicular to the first direction. The method defines regions within the geometric circuit layout. To do so, the method defines a first region having a perimeter positioned along the sides of the gate conductor where the gate conductor intersects the active area and then expands the perimeter of the first region in the second direction to edges of the active area to define a perimeter of a second region. The first region and the second share perimeters in the first direction. The method then expands the perimeter of the second region in the first direction to define a perimeter of a third region. The second region and the third region share perimeters in the second direction. The method then separately evaluates effects the other transistor elements have within each of the first region, the second region, and the third region, to determine a characteristic of the gate conductor.

摘要： A method and computer program product for modeling a semiconductor transistor device structure having an active device area, a gate structure, and including a conductive line feature connected to the gate structure and disposed above the active device area, the conductive line feature including a conductive landing pad feature disposed near an edge of the active device area in a circuit to be modeled. The method includes determining a distance between an edge defined by the landing pad feature to an edge of the active device area, and, from modeling a lithographic rounding effect of the landing pad feature, determining changes in width of the active device area as a function of the distance between an edge defined by the landing pad feature to an edge of the active device area. From these data, an effective change in active device area width (deltaW adder) is related to the determined distance. Then, transistor model parameter values in a transistor compact model are updated for the transistor device to include deltaW adder values to be added to a built-in deltaW value. A netlist used in a device simulation may then include the deltaW adder values to quantify the influence of the lithographic rounding effect of the landing pad feature.

摘要： Impact on parametric performance of physical design choices for transistors is scored for on-current and off-current of the transistors. The impact of the design parameters are incorporated into parameters that measure predicted shift in mean on-current and mean off-current and parameters that measure predicted increase in deviations in the distribution of on-current and the off-current. Statistics may be taken at a cell level, a block level, or a chip level to optimize a chip design in a design phase, or to predict changes in parametric yield during manufacturing or after a depressed parametric yield is observed. Further, parametric yield and current level may be predicted region by region and compared with observed thermal emission to pinpoint any anomaly region in a chip to facilitate detection and correction in any mistakes in chip design.
