Technical background
(1)Ferrotec has been engaged in precise cleaning for 18 years, accumulated a large number of mature cleaning BKM, and continued to improve;(2)Cooperate with world-renowned semiconductor equipment manufacturers to jointly develop leading cleaning technologies;(3)In the first quarter of 2019, a Research and Development Centre for precision cleaning will be established to enhance the capability of failure analysis and advanced process research and development.Clean environment
(1)Cu/Non-Cu is completely segregated by different production lines to reduce cross-contamination;(2)Segregate cleaning of different processes, dedicated ceramic and quartz cleaning line to reduce pollution; (3)The clean room adopts vertical flow mode, and the dust-free environment is easier to control; (4)Dry-wet separation is used in clean room to reduce the risk of cross-contamination.Equipment capability
