Whether producing simple metallic pads for probing exciting new nanoscale systems or structuring more complicated geometries into silicon and other materials, nanofabrication lies at the heart of much of the work at Brookhaven's Center for Functional Nanomaterials. Inside the nanofabrication facility are three bays filled with state-of-the-art equipment available for use by the CFN staff, the Brookhaven community and all external users. Nanofabrication is the design and manufacture of products and structures, especially electronic devices, with dimensions measured in nanometers. The technicians are wearing clean room suits (an overall garment worn in a clean room). The suit covers the wearer to prevent skin and hair being shed into a clean room environment.
