A technique used for integrated circuit fabrication in which a silicon slice is coated uniformly with a radiation- sensitive film, the resist, and an exposing source (such as light, x-rays, or an electron beam) illuminates selected areas of the surface through an intervening master template for a particular pattern.

A printing process in which a design is sketched with an oily ink or a litho crayon on a flat, smooth stone; in printing, the entire surface of the stone is wetted, and the design areas repel the water, but accept a greasy ink; a clean impression is then made by pressing a sheet of paper against the surface of the stone and running the whole through a press.
