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： System and method for compact model algorithms to accurately account for effects of layout-induced changes in nitride liner stress in semiconductor devices. The layout-sensitive compact model algorithms account for the impact of large layout variation on circuits by implementing algorithms for obtaining the correct stress response approximations and layout extraction algorithms for obtaining the correct geometric parameters that drive the stress response. In particular, these algorithms include specific information from search “buckets” that are directionally-oriented and include directionally-specific distance measurements for analyzing in detail the specific shape neighborhood of the semiconductor device. The algorithms are additionally adapted to enable the modeling and stress impact determination of a device having single stress liner film and dual-stress liners (two different liner films that abut at an interface).
