Abstract
A deposited film is processed in a preselected pattern by discharging electric energy through the film across a gas dielectric. In a preferred embodiment, a voltage pulse chain is applied to a moving probe spaced a preselected distance from the film. The discharge either removes the film material over the pattern to expose underlying material, or produces a conductive path from the top to the bottom of the film.
