==Supported processes==
In addition to these, this tool has a number of user-created recipes for etching a wide variety of materials. Some of these recipes are documented on [[LNF User:{{BASEPAGENAME}} User Processes|{{BASEPAGENAME}} User Processes]]. If you are curious if your material can be processed in this tool, please contact the tool engineers via the helpdesk ticket system.

Hardware Details

  • Broadband light source calibrated to 20 mJ/sec at the 405 nm peak. Total broadband dose ~30 mJ/sec
  • 4" and 6" chucks
    • Backside alignment piece chuck available with staff permission.
  • 4", 5" and 7" mask holders
  • Flood exposure, soft, hard, and vacuum contact capable
  • Capable of topside, backside and wafer to wafer alignment
  • 10 mm stage travel, 150 mm microscope objective travel with split field view camera option
