Monte Carlo simulation was applied to optimize the beam energy and pattern design prior to the experimental study.
Electron Beam Lithography (EBL) refers to a lithographic process that uses a focused beam of electrons to form the circuit patterns needed for material deposition on (or removal from) the wafer, in contrast with optical lithography which uses light for the same purpose. www.EESemi.com. developer solution, while the exposed areas of the negative resist
