Claim Text:
1. A method implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions operable to: derive an uplift factor as a function of a width of a single-finger semiconductor device for each leakage current component based on an amount of uncorrelated random variations in the leakage current component for one specific width of the semiconductor device and use the uplift factor as a multiplier for the leakage current component; when the semiconductor device is a single-finger transistor, use the uplift factor for sub-threshold drain current as a multiplier of the sub-threshold drain current so that a lowering of nominal threshold voltage of the single-finger device occurs in a single simulation run; derive a threshold voltage mismatch expression which is related to an amount of an uncorrelated random variation in sub-threshold drain current and which is not directly inversely proportional to a square root of the width of the single-finger device; use the uplift factors and the threshold voltage mismatch expression within a semiconductor device model to predict at least statistical characteristics of the leakage currents and use the deriving steps and the using steps in manufacturing an integrated circuit chip.
