DNA-Inspired Assembly of Nanoscale Electronic Devices
Abstract
The semiconductor industry produces electronic devices that drive all modern technologies. Due to the limitations of traditional lithographic manufacturing techniques, this industry has envisioned that nanoscale electronics will facilitate the continuation of Moore~s Law (i.e. the doubling of integrated circuit transistor density every two years) past the current limits of lithography. However, the fabrication of such electronics remains at a standstill due to three fundamental roadblocks: (1) The synthesis of large quantities of modular nanoscale circuit elements; (2) The creation of large area molecular breadboards with nanoscale precision; and (3) The high fidelity self-assembly of nanoscale circuit elements at such breadboards. The proposed effort will address these three roadblocks by establishing an unprecedented methodology for the massively parallel manufacture of nanoscale electronic devices. First, DNA-inspired nanoscale active circuit elements (diodes and transistors) will be designed and synthesized from organic semiconductor building blocks. Specifically, p-type and n-type organic semiconductor building blocks will be assembled in predetermined arrangements via standard DNA phosphoramidite chemistry. Molecular breadboards will then be nanoimprinted on solid substrates to serve as templates for the directed self-assembly of these DNA-like macromolecular constructs. Finally, the integrated devices will be extensively characterized, both physically and electrically, to confirm their suitability for semiconductor electronics. If successful, the proposed research will establish a new paradigm for the high throughput manufacturing of nanoscale electronic circuits at low cost and on a scale relevant for industrial and military applications.
