"Experimental fabrication. We want to change the way that people go from thinking about a device to making it in the lab. With ExFab, we will make that process faster and cheaper, with fewer restrictions on materials. It will allow the rapid prototyping of microscale and nanoscale devices in a time scale not typically associated with microelectronic fabrication, and it will bring together researchers from in engineering, medicine, and the basic sciences.
"With our investment in the tools and space, we can explore how it's used, and let that guide us in how to develop the space into the future."
ExFab emerged from a two-year process of faculty brainstorming about how best to address the need for new tools and processes for research in materials, electronics, and photonics. In addition, faculty also wanted to study how the new tools and space are used. The goal was to create an accessible space for faster, cheaper fabrication of a wider range of materials and processes.
Strategically located in the Allen Building near the engineering quad and the David Packard building, and across from the Medical School, ExFab is open to all: Stanford students and postdocs from all departments and schools, as well as researchers from other universities and industry.
Repurposing existing space, ExFab boasts several new tools, including those that can translate computer-generated images into physical microscale and nanoscale patterns within minutes. Many of these tools are housed in a reconfigured cleanroom. Complementing the System Prototyping Facility (SPF) – just a few steps away – students can easily utilize both areas to integrate fabricated devices into electronic systems.
In Spring, ExFab will be fully outfitted with equipment enabling researchers to define structures from the nanoscale (two-photon 3D printing) to the milli-scale (3D wax printing) and in between (direct-write lithography, aerosol jet printing) as well as to machine and meld disparate materials (laser cutting, CNC micromilling, grinding, bonding.) This toolset supports heterogeneous materials processing for emerging applications such as stretchable electronics, micro-batteries, photovoltaics, and microfluidics. With lower materials restrictions than a typical microelectronics fab, we anticipate the processing of a broad range of materials into devices and systems, including traditional semiconductors, soft materials, polymers, and bio-materials.
Nine months ago, excited for the potential of this proposed lab, over 30 faculty pledged they would use ExFab for their research, thus seeding this program. Now ExFab is a reality, and available to all. If you are an interested researcher or faculty, please email firstname.lastname@example.org or check out the website, snf.stanford.edu to learn more.
