Abstract:
A method of extracting n wherein n is a natural number greater than or equal to 2, model parameter sets in order to statistically simulate the operation and the performance of an integrated circuit design, the method comprising:designating n points in one or more wafer and forming an elementary device of the integrated circuit at each of the n points; creating an I-V characteristic curve by measuring the I-V characteristic of the elementary device formed at one point among the n points; using the I-V characteristic curve to extract a first model parameter set which reproduces the I-V characteristic curve within a predetermined error range; measuring a main characteristic data value of the elementary device formed at a kth, wherein k is a natural number from 2 to n, point among the n points; and extracting a kth model parameter set which converges on the main characteristic data value within a predetermined error range, wherein n model parameter sets are extracted by repeating the steps of measuring the main characteristic data value until k is equal to n, increasing k by one, and extracting the kth model parameter set.
