Web21 Dec 2015 · Polymethyl methacrylate (PMMA) is widely used in micro and nanofabrication as a very high resolution resist. It is extensively used for both electron beam lithography [1–3] and for x-ray lithography [4, 5].PMMA first emerged as a resist during the 1960s and has been popular ever since because of its many desirable properties. WebSoft lithography, inkjet printing, nanoimprinting, and polymer deep-pen lithography are primary lithography techniques employed to implement micro-patterns with QDs, however, there are limited reports on QD photolithography using conventional photolithography processes suitable for mass production.
