Abstract
Reducing the critical feature size and lowering the overall fabrication cost are the keys to the future of semiconductor manufacturing. There is great interest in the development of novel electronic device manufacturing technologies compatible with high-resolution, low-cost, and large-scale fabrication. DNA-based nanofabrication technology developed in recent years is able to meet the above needs, due to its unique set of characteristics: designable patterns, nanometer-level resolution, low cost and scalability. Based on these advantages of DNA-based nanofabrication, this technology has broad prospects in the fields of electronic device manufacturing.
This dissertation focuses on the application of DNA materials in the field of electronic device fabrication. Chapter 2 introduces the method of combining DNA-based nanofabrication technology with traditional doping technology. This method can realize n-type patterned doping by using DNA nanostructures as patterns and dopant carriers. Chapter 3 reports the use of DNA nanostructures as templates to deliver different dopants to achieve both n-type and p-type patterned doping, thereby expanding the usability of DNA materials for doping. Chapter 4 reports the application of DNA-based doping technology in the production of PN diodes, thus demonstrating the application of DNA nanomaterials in the production of analog electronic devices. Motivated by our interest to expand the doping study to 2D materials, Chapter 5 reports the changes in surface electrical properties of graphite materials over time in the air, allowing us to better understand the impact of air contaminations on the surface potential of graphite.
I hope this dissertation can provide more insights into the application of DNA nanostructures in the production of electronic devices, and lay a steppingstone for the application of DNA nanotechnology in the field of electronic manufacturing.
