The FPA-5500iZa i-line stepper combines high throughput, the ability to expose a scan field in a single shot, and a proven cost-effective platform. The 300mm-capable iZa matches leading KrF and ArF step and scan systems with a 4:1 reduction ratio and a 26mm x 33mm field size. It works faster and is more cost effective than either an i-line scanner or two small-field steppers that have to stitch (in which case, add the advantage of having a single footprint).
