WebNanofabrication technology is often conveniently classified on the basis of two basic approaches: top-down or bottom-up. Top-down approach is exemplified by conventional microelectronic processing technologies, while bottom-up approach is uniquely associated with the rapidly growing suite of alternative nanofabrication methods. WebTop-down fabrication is highly flexible and adaptable, but has limits on the dimensions of the fabricated patterns and can often induce damage or irregularities into the nanoscale structures. Examples of top-down nanofabrication techniques include electron-beam lithography, ion implantation, and reactive-ion etching.

Nanomanufacturing is both the production of nanoscaled materials, which can be powders or fluids, and the manufacturing of parts "bottom up" from nanoscaled materials or "top down" in smallest steps for high precision, used in several technologies such as laser ablation, etching and others. Nanomanufacturing differs from molecular manufacturing, which is the manufacture of complex, nanoscale structures by means of nonbiological mechanosynthesis (and subsequent a… Web29. mar 2016 · A top-down nanofabrication approach is used to develop silicon nanowires from silicon-on-insulator (SOI) wafers and involves direct-write electron beam lithography … Web29. mar 2016 · The top-down nanofabrication process of silicon nanowires is briefly illustrated in Fig 1.
