1 January 1992 Improved performance of a CORE-2100 through a joint development program

New semiconductor device technologies demand ever tighter critical dimension (CD) control in mask and reticle production. With this in mind ATEQ and Micro Mask began a joint development program that led to changes in calibration and operating parameters, and several hardware replacements on the CORE-2100. This effort led to improvements in two technology modules key to the CORE-2564 product: the rotating polygonal mirror and the steering mirror servo loop. Analysis techniques used to identify error contributors include both linewidth and placement metrology. Both CORE-2100 and CORE-2500 product generations benefit from these improvements, especially in the area of isolated and packed pitch feature uniformity.
