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 anisotropic polymer etching, III-V's and a variety of other materials.

Capabilities

A wide range of materials can be etched:

• Anisotropic cyro polymer etching
• GaN
• GaAs
• Aluminum

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 the User Manual above.
3. Complete the process request form.
4. Create a helpdesk ticket requesting a checkout session.
5. Authorization will be provided pending successful completion of the quiz and demonstration of proper tool use in the presence of a tool engineer.

Maintenance

Once a month the chamber is cleaned and the tool inspected.
