The "Fab on a Chip" approach is a novel fabrication technique that leverages the control and stability of MEMS machines to fabricate structures on the nano-scale. This contrasts to standard deep-UV and e-beam lithography methods typically used today. We are developing a method of nano-fabrication that can be operated in a cryostat to enable novel physics experiments at low temperatures. To this end, we build MEMS-based machines that mimic typical macroscopic tools found in a modern nano-fabrication facility. In a very real sense, we are using macro machines to build micro machines and then micro machines to build nano devices and structures. Our ultimate goal is a fully integrated "Fab on a Chip" where on a single chip, one has all of the needed elements to assemble and test nano devices. In my talk I will discuss the approach and our progress to date.
