AN AUTOMATIC STEP-AND-REPEAT CAMERA,
Abstract
The report describes an automatic step-and-repeat camera for integrated circuit fabrication. This step-and repeat camera has a continuously variable reduction ratio with final size and focus directly controlled in the camera. Any angular misalignment of the image is corrected without external instrumentation. The control system and other associated components were chosen to minimize cost. The camera is adequate for research laboratory where problems of high rate of mask production are not encountered. It is capable of handling 1/4-mil dimensions as they appear in silicon integrated microcircuits. (Author)
