发明名称 Method and system for enhancing yield of semiconductor integrated circuit devices using systematic fault rate of hole
摘要 A method of enhancing yield of semiconductor integrated circuit includes determining multiple experimental values, each experimental value corresponding to a distance from a side of a hole to an opposing side of a shape surrounding the hole, forming test patterns representing each of the experimental values on a wafer and calculating experimental value-based systematic fault rates from the test patterns; converting the experimental value-based systematic fault rates of the hole into the experimental value-based systematic fault rates, calculating a length of a side of the hole for which a distance between the side of the hole and the opposing side of the shape corresponds to each of experimental values, and calculating a systematic fault rate of the hole using the experimental value-based systematic fault rates per unit hole length and the length of the sides of the hole calculated for the respective experimental values in the desired layout.
