Nanofabrication Process

Briefly "top-down" techniques start from bulky silicon that is shaped down to the required size and morphology through lithographic mechanisms assisted by etching processes In particular nanolithography techniques such as electron-beam lithography (EBL) and nanoimprint lithography followed by reactive-ion etching or wet anisotropic etching processes are utilized ( Park et al 2010
