ASx Series

Photomask Processing Platform for advanced Bake, Resist Strip & Clean and Develop

The ASx series is SUSS MicroTec’s photomask processing platform for 250nm to 90nm technology nodes with advanced bake (qualified up to current technology node), clean, develop and etch technologies. The series offers reliability, stability and performance to meet critical challenges of defect-free processing of masks exposed to 248nm and 193nm lithography.

Highlights

Highest first pass cleaning yield, resulting in extended mask life

Low cost of ownership with small footprint (1200 x  1200mm)

High reliability and uptime

More than 250 ASx Sold

State of the Art Advanced Bake - Qualified up to Current Technology Node

Advanced Single Substrate Cleaner ASC 5500
