Digital Information Technology (IT), once it replaced our analog IT, provided unbelievably complex and amazingly reliable IT systems. Nanotechnology is currently at a comparable stage as IT was where the majority of information processing was analog. Today the promises of nanotechnology are largely unfulfilled, but that will change with a 2nd Digital Revolution: Digital Atomic Scale Fabrication. For many of the reasons that Digital IT is vastly superior to analog IT, digital fab, where digital events are the making/breaking of chemical bonds, will be remarkably better than analog fab. Our ultimate goal at Zyvex Labs is the development of Atomically Precise Manufacturing where inevitable fabrication errors are detected and corrected. This technology will provide the nano-foundries required to produce the nanotechnology products that have been promised but not delivered. Digital atomic scale fabrication is not only a sound idea, it is inevitable. I will describe a promising candidate technology.
