The Acid Bench 92 is a multi-process acid bench. It houses several plating processes as well as wafer cleaning processes like piranha, HF and PFC and etches like the HF-Nitric and multiple metal etches. There is no restriction on the materials allowed. There is a strict separation (segregation) in the glass ware to be used depending on the process and all the metal samples are first rinsed in the sink before doing the last clean in the QDR. The QDR is regularly cleaned with sulfuric and the aqua regia mixture in order to keep it ion-free. There is an spinner drier (SRD) associated with this bench for the last cleaning step.

The Acid Bench 92 is designated as a Undefined 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 email@example.com 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 Acid Bench 92 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.
