Abstract :
In this paper, a method is described which can be used to predict the variation of circuit performance, e.g. the maximum clock rate, due to fluctuations of the semiconductor manufacturing process, A huge amount of measurements on CMOS test devices of two process generations (0.8 and 0.5 micron) has been performed to develop a description of the statistical variations. Based on this data and the use of a physical simulation model for the MOS devices, a prediction of the circuit performance of two future CMOS process generations (0.35 and 0.25 micron) has been undertaken. At least, the results of this study will be applied to a special type of circuits, to predict the feasibility of synchronous clock and data distribution on future ULSI devices
