Announcements

Currently, use of this tool is restricted to users with high priority deadlines and who are assisting with etch rate characterization. If you believe your process falls into these categories, please create a helpdesk ticket. There will be extensive initial training and practice due to the limited documentation currently published for the tool.

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.
