The LAM 9400 SE is a high density plasma etch tool manufactured by LAM Research Corporation. This tool was originally designed for production polysilicon etching, but has been reconfigured for silicon based materials, III‐Vs, some metals, and organic materials. It uses a TCP (transformer coupled plasma), which is a special patented form of an ICP source to enhance plasma density. It also has a bias power supply for controlling ion bombardment energy.

The LAM 9400 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 firstname.lastname@example.org for any material requests or questions.
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 LAM 9400 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.
Standard Operating Procedure
Widget text will go here.
- Read through the Standard Operating Procedure above.
- Complete the training request form here.
- Create a helpdesk ticket requesting training.
- A tool engineer will schedule a time for initial training.
- Practice with your mentor or another authorized user until you are comfortable with tool operation.
- Complete the SOP quiz here.
- 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.
To verify the condition of the tool, a bi-weekly blanket Oxide 120 sec etch is run and the etch rate recorded. This chart shows the etch rate over time.
