Lithography Concerns

In order to maintain full warranty coverage for steppers, manufacturers require tool owners to meet explicit air and purge gas contamination specifications. Additionally, periodic analyses of refractory compounds are also required. In order to fulfill these requirements, Balazs offers stepper/scanners environment analyses to meet ITRS and OEM requirements.
