Lithography printing Britannica
WebSince lithography for device fabrication involves the use of optical exposure to create the pattern, semiconductor lithography is commonly called "photolithography". As with the inspection and metrology techniques already discussed, photolithography is the technique of choice for patterning because it is optical, and thus enables small features and high … WebHow to tell a Lithograph from a print. You will need a magnifying glass and a little experience but what you need to look for is a series of tiny dots. If the dots look even in size and evenly spread apart to make up the image (think like an inkjet printer) then that would most likely be a mechanical print. If the dots look more random in size ... diamorphos
