Abstract

A substrate for integrated components including a support structure and a thin non-conductive film. An intermediate film is placed between the support structure and the thin non-conductive film. The intermediate film is a sacrificial film which may be removed chemically. By doing so, the thin non-conductive film may be liberated from the support structure. The intermediate film is traversed by channels which carry the chemicals for removing the sacrificial film. The channels may form a grid on the surface of the intermediate film.
