NanoFab Operating Procedures

Chemicals and Supplies

The NanoFab keeps on hand an inventory of basic processing supplies including tweezers, silicon wafers, gelpaks, and cleanroom notebooks. These supplies may be purchased by customers with a NEMO account by contacting any NanoFab staff member. Supplies are stocked and sold in limited quantities. This service is offered as a convenience to customers who have an immediate need, and should not be considered a primary means of procurement.

The NanoFab also keeps on stock the most common variants of wet chemicals used for photo lithography, wet etching, and general nanofabrication processing. Chemicals are provided on an as needed basis to users. In most circumstances the costs for chemical use are included in the "base cleanroom" rate. Chemical use in the NanoFab is strictly limited to preapproved substances and must be performed in defined areas. Questions regarding the list of currently acceptable substance should be directed to the NanoFab manager. A detailed description of chemical handling SOPs can be found in the NanoFab safety manual.

User Storage

The NanoFab provides active cleanroom users with in lab storage. The storage area consists of a large rack that is divided into individual bins. We supply large plastic containers that fit inside each bin. We ask that users limit their supplies to what safely fits into one bin. If this poses a significant problem for you, please let me know so we can help you find a different storage strategy. New bins can be assigned any time after a new user completes cleanroom certification by contacting nanofabuseroffice [at] You will be asked to provide your NEMO userid and contact information.
