Abstract: The present invention provides a simple method for ablating a protective thin film on a bulk surface and roughening the underlying bulk. In an embodiment, silicon nitride thin films, which are useful as etch-stop masks in micro- and nano-fabrication, is removed from a silicon wafer's surface using a hand-held “flameless” Tesla-coil lighter. Vias created by a spatially localized electron beam from the lighter allow a practitioner to perform micro- and nano-fabrication without the conventional steps of needing a photoresist and photolithography. Patterning could be achieved with a hard mask or rastering of the spatially confined discharge, offering—with low barriers to rapid use—particular capabilities that might otherwise be out of reach to researchers without access to conventional, instrumentation-intensive micro- and nano-fabrication workflows.
