The Center for Nanoscale Materials offers nanofabrication capabilities in a 18,000-square-feet cleanroom with comprehensive lithographic, deposition, etching, and metrology suites, suitable to meet all user needs from small samples up to wafer-scale fabrication.

We pioneer new cleanroom-based nanofabrication techniques to integrate novel materials into unique structures and devices to realize nanofabricated structures for the transduction of mechanical, optical, and electrical signals.

We study the fundamental science behind the operation of micro- and nanoscale systems with the goal of achieving unprecedented control in the fabrication, integration, and manipulation of nanostructures and enhancing their performance and range of use.

We also operate a 18,000-square-foot class 100 and 1,000 cleanroom that includes the following nanofabrication features:

  • Lithography Suite: Variable voltage and 100-kV electron beam lithography, 150 mm stepper, Ga ion beam, and direct write optical and holographic lithography capabilities, as well as contact printing with back-side alignment.
  • Deposition Suite:

    • Multi-chamber industrial plasma-enhanced chemical vapor deposition, multi-chamber sputtering tools, electron beam evaporation including ultra-high rate, and high-density chemical vapor deposition.
    • Atomic layer deposition of dielectrics and metals.
    • Microwave-plasma chemical vapor deposition for production of diamond films and a system for production of carbon nanotubes and graphene.
  • Dry Etch Suite:

    • Multichamber industrial reactive ion etcher, deep reactive ion etching, dual chamber inductively coupled reactive ion etcher, several single chamber etchers, and down-stream plasma ashing.
    • o Non-plasma etching, including XeF2 dry etching of silicon and vapor HF etching of SiO2.
    • Focused-ion beam etching using Ga.
  • Wet Etch Suite: Electroplating, an electrochemical workstation, automated lift-off bench, and supercritical drying capability for postprocessing.
  • Supporting Suite:

    • Metrology tools, including profilometers, reflectometers, confocal microscope, stress gauge at variable temperature, a spectroscopic ellipsometer, and atomic force microscopy.
    • Scanning electron microscopes, including energy-dispersive X-ray spectroscopy.
