The Oxford Plasmalab System 100 is a 100 mm reactive ion etching tool designed for a variety of etches. It’s an ICP based etcher designed to etch pieces mounted to a 100 mm wafer. The diameter of the source only allows it to uniformly etch the center ~1.5” of the wafer, making it perfect for pieces. With a variety of gases and a cryo chuck it is ideal for XYZ.

Material Restrictions

The Oxford Plasmalab System 100 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 info@lnf.umich.edu for any material requests or questions.

Supported Processes

There are several processes for this tool supported by the LNF, which are described in more detail on the Processes page.

In addition to these, this tool has a number of user-created recipes for etching a wide variety of materials. Some of these recipes are documented on Oxford Plasmalab System 100 User Processes. If you are curious if your material can be processed in this tool, please contact the tool engineers via the helpdesk ticket system.
