WebAug 23, 2008 · The fine structures are written into the resist layer by e-beam lithography, immediately followed by UV exposure (i-line) of larger structures. Subsequently, resists are developed in one step according to the usual protocol. A maximum resolution of < 10 nm can be realised for very thin films with AR-P 7400 and AR-N 7520. WebJust like in photolithography, the purpose of electron beam lithography is to generate very small structures in the resist which can then be transferred to the substrate material, mostly through etching. The major benefit of this type of maskless lithography is that it can create custom shapes (direct-write) with sub-10 nm resolution.
