Another new tool, an Oxford Instrument, RIE-ICP Plasma Pro S100 (Cobra) has been ordered, which will be installed in the cleanroom 174. This tool is capable of high aspect ratio submicron etching using the cryogenic and Bosch processes. Various etch chemistries are possible which include Cl2, BCl3 and SF6 gases.

This course covers geometrical and physical optics; interference; diffraction; polarization; microscopic origins of macroscopic optical properties of matter; optical activity; electro-optical, magneto-optical, acousto-optical phenomena; spontaneous Brillioun, Raman, Rayleigh scattering. We will be working our way through the very practical Optics textbook by Hecht. - John P. Prineas, Associate Professor, UI Dept. Physics & Astronomy

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...

The annual symposium is designed to present the general public and University professionals with up-to-date knowledge about activities of OSTC groups and allow OSTC group members to become re-acquainted with the activities of others, often generating renewed interest and sparking new collaborations and interactions. Morning speaker session, luncheon and an afternoon poster session will take place. Please check OSTC website for registration details.

In 1995, the Optical Science and Technology Center (OSTC) was founded as an interdisciplinary center with a mission to develop a home to further the academic programs in optical science basic research and applications at the University of Iowa. Today, OSTC has grown to 26 faculty members from the departments of Biological Science,...
