IVS
The IVS 220 system is the latest generation in the IVS series and has been designed for ultimate precision, TIS (tool induced shift) and throughput on 200mm wafers. The cornerstone of the system’s reliability and stability is its mean time between failure (MTBF) of 2,100 hours. The IVS 280 provides the same capability in a package designed for overhead track handling with full E84 GEM300 capability.
