Quattrone Nanofabrication

Leading-Edge Nanofabrication

The Quattrone Nanofabrication Facility supports nanoelectronics, nanomaterials development and integration, soft matter, microfluidics and MEMS/NEMS.

QNF resides in the Krishna P. Singh Center for Nanotechnology. By providing core nanofabrication capabilities, our mission is to enable research and development in a number of areas. As embodied in the Penn Compact, QNF focuses on increased access, as well as integrating knowledge by engaging the Greater Philadelphia Region and far beyond. Our core endeavors are to support teaching, research, service and commercialization at the micro- and nanoscale.

QNF staff operates a 10,000sq.ft. cleanroom with leading-edge equipment capable of electron-beam and optical lithography, physical and chemical vapor deposition, dry and wet processing, metrology, and device characterization. In addition, a complimentary facility for soft materials and laser micromachining is maintained by QNF for diverse materials processing, microfluidics and lab-on-chip activities. For device packaging and hybridization, there is a suite of backend equipment available for wirebonding, wafer bonding, electrical testing and wafer dicing.
