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 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 designated as a Semi-Clean class tool. Below is a list of approved materials for the tool. Approved means the material is allowed in the tool under normal circumstances. If a material is not listed, please create a helpdesk ticket or email firstname.lastname@example.org for any material requests or questions.
There are several processes for this tool supported by the LNF, which are described in more detail on the SPR 220 and SPR 955 pages. The tool is already equipped with various recipes for spin coating at different thicknesses, developing at different times and baking at different temperatures. If the tool is not equipped with a recipe that you need, then please create a helpdesk ticket.
Standard operating procedure
Widget text will go here.
- Complete a Lithography training session. If you have already completed this for another tool, you do not need to complete it again.
- Read through this page and the Standard Operating Procedure above.
- Practice with your mentor or another authorized user until you are comfortable with tool operation.
- Complete the SOP quiz here
- Create a Helpdesk Ticket requesting training/checkout.
- A tool engineer will schedule a time for training/checkout
Complete spinner clean is done monthly. Fluid and resist are checked/filled weekly. Hot plate ovens cleaned bi-weekly or as needed. Spray developer is checked/filled weekly. Robot training performed annually or as needed.
