Wafer imaging technology has changed significantly in the past few years, responding to the demands of LSI and VLSI circuitry. The powerful driving force of economics indicates that the LSI trend will continue with reduced line widths and greater complexity to achieve a higher level of functions in reduced area. Even with signigicant cost increases due to advanced equipment and zero defect mask or wafer fabrication, increased integration is cost effective and progression toward sub-micron design rules is expected to continue. 1 The major question is how sub-micron technology will be implemented into the production environment.
