2D laser lithography on silicon substrates via photoinduced copper ...

WebAdvantages of Photolithography. Photolithography can create patterns with extremely small features – down to a few tens of nanometers – while also enabling incredibly precise control over feature geometry. Photolithography is also comparatively fast, capable of creating patterns over an entire silicon wafer with relatively low cost. WebCharacteristic #2: There is a plate impression. An important visual clue is the presence of a plate impression. Because the ink of a photogravure is transferred from the copper plate to the dampened paper under pressure from the press, the edges of the plate itself create an impression on the paper.
