Brief Abstract: Chemists can now construct wires which are a few atoms in diameter; these wires can be selectively field-effect gated, and wire crossings can act as programmable diodes. The tiny feature sizes offer a path to economically scale to atomic dimensions. However, the associated bottom-up synthesis techniques only produce highly regular structures and have high defect rates and minimal assembly control. We develop architectures to bridge between lithographic and atomic-scale dimensions and tolerate defective and stochastic assembly. Using 10nm pitch nanowires, these nanowire-based programmable architectures offer one to two orders of magnitude greater mapped-logic density than defect-free lithographic FPGAs at 22nm.
