Microfabrication Cleanroom


About Us

IMR maintains and operates a micro-electro-mechanical systems (MEMS) fabrication facility located on the Pullman, WSU, campus in the Engineering Teaching and Research Laboratory building. It is a class 1000 cleanroom that is approximately 1000 ft2.

A brief description of the available equipment is described here and shown in the map below. The facility houses typical MEMS fabrication instruments and equipment which includes a spin coater, mask aligner, wet benches, sputter machine, reactive ion etcher, deep reactive ion etcher, plasma etcher, profilometer, ellipsometer, tube furnaces and a rapid thermal processor. The sputtering machine is an Edwards Auto 306 and is able to deposit thin, uniform layers via chemical vapor deposition (CVD). The sputter machine utilizes two power supplies (DC and RF) and two magnetron sputter guns. Also, the machine has a thin film thickness monitor that can accurately calculate film thicknesses to the order of tens of nanometers. We also have an Atomic Layer Deposition (ALD) machine.
