WebHere, we introduce a general chemical approach for photoresist-free, direct optical lithography of functional inorganic nanomaterials. The patterned materials can be metals, semiconductors, oxides, magnetic, or rare earth compositions. No organic impurities are present in the patterned layers, which helps achieve good electronic and optical ...

Webwaveguides were generally fabricated by using E-beam lithography and stepper. It would be very attractive if the highly accessible UV contact lithography can be accommodated to fabricate low loss waveguides. However, the resolution limit of direct contact lithography is larger than 1µm due to optical diffraction limit. Even for large Webgeneration lithography is SCALPEL® (SCattering with Angular Limitation Projection Electron-beam Lithography).2,3 SCALPEL is a reduction image projection technique which uses 100 keV electrons and scattering contrast. The use of electrons circumvents the limitation of diffraction in optical lithography. The principle is illustrated in Fig. 2 ...
