IEN - Micro/Nano Fabrication Facility
Processing Materials

The chemicals listed in the tables below are common chemicals (i.e. photoresist, developers, acids, etchants, bases, & solvents) found in IEN cleanroom facilities. For a more comprehensive list for chemicals and associated files (e.g. SDS, technical datasheets) please refer to the chemical section in IEN department chemical tab on SUMS page. Manufacturer's websites are also good references to find out more specific processing information.

Understand the possible reactions when mixing chemicals.

Many processing steps require mixing liquid chemicals together. Users should make themselves aware of the chemical reactions possible when mixing chemicals in order to minimize the risk to themselves and others around.

For example, always add acids to water. Adding water to an acid causes a highly exothermic reaction which can cause a fire and release dangerous gases into the air.
