Abstract
VLSI and ULSI developments aimed at sub-micron geometries require improved measuring systems. A computer controlled cassette to cassette electron beam system has been developed. High resolution of l5nm at lkV is routinely achieved with a unique 4 lens electron optical system. Through-put of the system is 10-15 wafers per hour (5 chips, 1 measurement/chip). An automatic line width measurement method with high accuracy, "The Linear Regression Method"1, has achieved an absolute accuracy of 0.009μm.
