The YES-310TA (E) (scheduler name Image Reversal Oven) is an image reversal and vapor prime oven designed by Yield Engineering Systems. It can vapor prime wafers with HMDS in order to improve photoresist adhesion. It can also perform image reversal via NH3. The large oven chamber can easily accommodate anything from a piece to a box of wafers.

Checkout procedure

Follow this procedure to receive authorization to run supported processes. Practicing with an authorized user or staff member prior to checkout is strongly encouraged.

  1. Complete a lithography training session. If you have already completed this for another tool, you do not need to complete it again.
  2. Read through this page and the User Manual above.
  3. Accurately complete the checkout quiz. You may retake as necessary until all answers are correct.
  4. Schedule a time for a checkout:
    1. Find an available time for checkout.
    2. Verify that the tool is available in the LNF Online Services at the time you are requesting.
    3. After confirmation that the event is scheduled in Calendly, invite the staff member assigned to your event to a Staff Support reservation at that time.
  5. Create a helpdesk ticket for final confirmation of your checkout appointment.
  6. Authorization will be provided pending demonstration of proper tool use in the presence of a tool engineer.

Maintenance

The YES Image Reversal oven is cleaned and maintaned as needed. The HMDS level is checked regularly and refilled when low. Any relevant information regarding tool maintenance is captured in the user logbook or announced via email and the Announcements section on the LNF wiki page.

User authorized maintenance

In the event of a power bump, users may restart the tool by following the Startup/Shutdown Procedure.
