2. The art of engraving on precious stones.
3. The art or process of making a drawing, design, or writing on a special kind of stone (called lithographic stone), so that impressions in ink can be taken from it.
Also, a planographic printing process using metal or plastic plates with a sensitized coating on which the matter to be printed is fixed chemically, before the non-printing areas of the plates are dampenedd and the remainder printed with greasy inks on flat-bed or cylinder presses.
2. The practice of scanning a beam of electrons in a patterned fashion across a surface covered with a film called the resist, exposing the resist, and of selectively removing either exposed or non-exposed regions of the resist called, "developing".
3. Lithography in which the radiation-sensitive film or resist is placed in the vacuum chamber of a scanning-beam electron microscope and exposed by an electron beam under digital computer control.
After exposure, the film is removed from the vacuum chamber for conventional development and other production processes.
