The [[{{PAGENAME}}]] is an automated [[photoresist]] [[Lithography|coating, baking, vapor prime, stripping and developing]] tool.  It can run full 4" and 6" cassettes of up to 25 wafers at a time.  It's capable of having multiple paths running simultaneously (ie., coating and developing from two different cassettes).  It automatically pumps [[SPR 220]]-(3.0) and [[SPR 955]] photoresists.  Other resists can be set up to automatically dispense from a syringe.  The spinner's closed lid option can help aid with more uniform sidewall coating.  [[HMDS]] is applied via vapor prime.  Both developers are CMOS compatible ([[MF 319]], and [[MF 300]]).  The developer temperature is controlled to within 0.1°C throughout the process.

The ACS 200 cluster tool is an automated photoresist coating, baking, vapor prime, stripping and developing tool. It can run full 4" and 6" cassettes of up to 25 wafers at a time. It's capable of having multiple paths running simultaneously (ie., coating and developing from two different cassettes). It automatically pumps SPR 220-(3.0) and SPR 955 photoresists. Other resists can be set up to automatically dispense from a syringe. The spinner's closed lid option can help aid with more uniform sidewall coating. HMDS is applied via vapor prime. Both developers are CMOS compatible (MF 319, and MF 300). The developer temperature is controlled to within 0.1°C throughout the process.

Capabilities

  • Automated spin coating
  • Automated spray developing
  • Automated vapor prime
  • Photoresist stripping
  • 4" and 6" wafers
PMMA and other e-beam resists should be processed in Photoresist Bench 31 in 1480A
Any other non standard photoresist must have direct approval of tool owner
SU-8 may only be processed in the ROBIN lab

System overview
