What the facility does

Fabrication and characterization of nanostructures

Area(s) of Expertise

The NanoFab is a state-of-the-art nanofabrication and characterization facility. Lithographic capabilities include contact optical and electron-beam lithography. Focussed ion beam milling is also available using a Ga/He system, which incorporates a gas-injection system for focused ion beam assisted deposition of metal and dielectric. Microscopy capabilities include optical microscopy (2 systems), stylus profilometry, scanning electron beam microscopy (2 systems), atomic force microscopy (2 systems), and focused ion beam microscopy (He). Material etching (Si and III-V) is provided by one reactive ion etching system, one inductively-coupled deep reactive ion etching system and an O2 plasma system. Material deposition is available through spin-coating and curing, sputtering, or evaporation (thermal or e-beam). Optical parameter characterization is provided by a scanning spectroscopic ellipsometer and a prism-coupled system. Back-end processing is enabled by a dicing saw, an end polishing system and a solder reflow system. 

Research Services

The NanoFab operates as an open access user facility. Students, researchers and external users are granted full access to the tools after appropriate training. Fee-for-service fabrication and characterization are also available to internal and external users. Typical projects include: the fabrication of integrated optical structures, silicon waveguides, plasmonic waveguides, metasurfaces, photonic crystal waveguides, photodetectors, modulators, lasers and biosensors.
