The University of Iowa

IMPORTANT: The Optical Science and Technology Center and Microfabrication Facility are being retired after fall 2018 and their services reconfigured under the new Iowa Center for Research, Exploration, and Advanced Technology in Engineering and Sciences (Iowa-CREATES) and Materials Analysis, Testing, and Fabrication (MATFab) in the Iowa Advanced Technology Laboratories (IATL) in spring 2019. As a result, the OSTC/UIMF site will eventually be taken down. Until then, please visit the Iowa-CREATES Website at, or read more about the new center at

UIMF Renovation

Monday, July 22, 2013

After several months of careful design and planning, the lab space in IATL 174 culminated into an ISO 5 (Class 100) cleanroom, which is now officially opened to users from May 2013. The renovation work involved the re-routing of ducts, existing building services and the install of services such as compressed air, chilled water and power. This cleanroom houses a wide range of thin-film deposition and etching tools for device fabrication at the micron- and nano-scale. Users are taught the cleanroom operation protocols before accessing the lab. Users can now carry out their fabrication in an ultra clean environment and have less concerns about process or device contamination.

In addition, plans are under way to renovate the adjacent lab, IATL 172 to construct a similar cleanroom to house a Direct-write Electron Beam Lithography system, capable of writing and imaging features on the nanoscale.
