Substrate requirements

Material restrictions

The Nanoquest II Ion Mill is designated as a Metals 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 info@lnf.umich.edu for any material requests or questions.


Supported processes

Initial characterization data for several recipes provided by the vendor are shown in the table below. Data is for thermal oxide and SPR 220. Uniformity data is from the thermal oxide measurement on 150 mm wafers with 10 mm edge exclusion.

Standard operating procedure

This SOP is still currently a draft. Please use caution when using the tool and take note of any additional information or changes provided by the tool engineer.

Widget text will go here.

Checkout procedure

  1. Complete the sample mounting course. If you have already completed this for another tool, you do not need to complete it again.
  2. Read through this page and the Standard Operating Procedure above.
  3. Complete the process request form.
  4. Create a Helpdesk Ticket requesting training.
  5. A tool engineer will schedule a time for initial training.
  6. Practice with your mentor or another authorized user until you are comfortable with tool operation.
  7. Schedule a checkout session with a tool engineer via the helpdesk ticket system. If this checkout is successful, the engineer will authorize you on the tool.
