Solid State Materials & Devices Research Laboratory

This is a 3000 ft² class 1000 clean room to support the fabrication and characterization of electronic, magnetic, optical and microwave materials and devices. Equipment for processing include systems for atomic layer deposition, RF sputtering, ion beam sputtering, thermal and electron beam evaporation, activated reactive evaporation, plasma-enhanced chemical vapor deposition, reactive ion etching, rapid thermal processing, wet chemical processing, and photolithography. Also available, for a user fee, are optical mask generating and direct write lithography capabilities. Characterization equipment includes optical and mechanical thin film measurement systems, Auger electron spectroscopy, scanning electron spectroscopy, and measurement systems for the electrical and microwave analysis.

Microwave Laboratory

This facility provides extensive equipment for time-and frequency-domain measurement and characterization of active and passive devices and structures, including electronic packaging and interconnects. The equipment list includes sampling oscilloscopes with multiple 20 GHz sampling heads, spectrum analyzers, noise figure meter, probe station, and electromagnetic interference (EMI) measurement systems. In addition to the measurement equipment, microwave design software suite and electromagnetic simulators are available.

Machine Shop

The College of Engineering at Oregon State University maintains a fully equipped machine shop with a full time machinist in support of research activities. This facility is available on a fee basis. In addition, a 3D printer (Dimension BST 1200) for creating ABS plastic components is accessible for research applications.

Oregon Nanoscience and Microtechnologies Institute (ONAMI)

ONAMI Facilities Weblink

As a member of ONAMI, the research team also has access to the facilities of all participating institutions namely, OSU, Portland State University (PSU), University of Oregon (UO) and Pacific Northwest National Laboratory (PNNL). These facilities lie within at most a 4-hour drive from Corvallis. Relevant equipment available at these institutions include: solid state lasers, atomic force microscope (AFM), magnetic force microscope (MFM), electron microscope and a SQUID magnetometer.
