Abstract
The joint IBM and Siemens 64 megabit development program has recently demonstrated successful fabrication of a 64 megabit prototype DRAM. Ev en with significant reduction in groundrules compared to the 16 Megabi t DRAM, a photolithography process was developed and implemented with a high degree of success. This paper describes the tool set, the proce ss and its performance and some of the issues faced in achieving this accomplishment.
