概要（Overview）

The PAS 5000/55A steppers feature a 0.48NA i-Line lens with a 21.2mm field, optimized for 0.5µm resolutions across IC productions and substrates like Silicon to GaAs. It boasts superior overlay performance due to its fast linear-electric exposure stage and phase grating alignment system. User-friendly software streamlines metrology tests in multi-stepper setups, promoting design rule optimization and enhanced yield. With only two alignment marks required, alignment time is minimized. Its swift stage and lack of need for send-ahead wafers guarantee peak productivity and precision. Additionally, it integrates a SMIF-compatible, high-speed reticle management system.
