Abstract

By using all-single-wafer processing in the 300 mm QTAT production system, we have shortened cycle time to 1/2 or less compared with mixed-batch processing. We have also developed a high-speed AMHS for realizing a short cycle time. An intra-bay RGV developed for the 300 mm fab is a component of this system. This paper describes the new system concepts, including AMHS hardware improvement, operation methods, and technician skill enhancement. Trecenti Technologies realized a transfer time of 1/3 or less that of previous fabs.
