Inventor: PFORR RAINER DR
IPC: G03F9/00
Filed: 1991-03-14
Abstract: A process for reducing masking errors due to the equipment in a projection, adjustment and exposure unit for the exposure of substrates operating on the on-axis masking principle. An arrangement of x, y and phi basal adjustment marks which form basic adjustment marks, is produced on a test substrate using semiconductor technology, the substrate is processed using semiconductor and image-forming processes, the basic adjustment marks are then covered successively with the masking system of the exposure unit, and the coordinates of the actuator in the aligned state of controlled masking are determined by means of a position measuring device. The values determined are stored in the memory of a computer, and the relative distances are subsequently determined from these stored values and are themselves stored. The calibration values derived therefore are determined, for detuning the x, y and phi channels of the masking system. The calibration values form control signals for an actuator which can be positioned with great accuracy. The actuator is pref. a laser path system coupled to the substrate platform, and is calibrated. USE/ADVANTAGE - The invention is used in the mfr. of high density integrated circuit components.
