Equipment Training
Training is offered weekly on a per need basis specially when there are new users. Please check the Training Schedule or contact the tool manager. Make sure before you request contact aligner training you have completed “General Lithography Training”, since it is a prerequisite.


ABM's High Resolution Mask Aligner is a very versatile instrument with interchangeable light sources which allow Near-UV (405-365 nm) as well as Mid- and Deep-UV (254 nm, 220 nm) exposures in proximity (non-contact) or contact (soft & hard) modes. The exposure can cover an area 200 mm in diameter. The bottom-mount mask system accommodates masks up to 9 inches square and substrates from small chips to wafers up to 200 mm. The alignment tooling system also features an air-bearing substrate-to-mask planarization system for wedge-error compensation. The printing resolution is 0.8 µm for Near-UV and 0.4 µm for Mid-UV and Deep-UV in vacuum contact mode. Exposures in Mid- and Deep-UV require quartz masks.


  • Hard or Soft Contact Modes
  • Any size or shape sample up to 200mm and 0.250in.
  • UV, Mid-UV, and DUV Exposure Modes
  • Split-field CCD Zoom Microscope Alignment System
  • Bottom-mounting Mask Holders
