Abstract: 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.

Abstract: A system and method for modeling a semiconductor transistor device structure having a conductive line feature of a designed length connected to a gate of a transistor device in a circuit to be modeled, the transistor including an active device (RX) area over which the gate is formed and over which the conductive line feature extends. The method includes providing an analytical model representation including a function for modeling a lithographic flare effect impacting the active device area width; and, from the modeling function, relating an effective change in active device area width (deltaW adder) as a function of a distance from a defined edge of the RX area. Then, transistor model parameter values in a transistor compact model for the device are updated to include deltaW adder values to be added to a built-in deltaW value.
