Abstract

A process of forming a resistive device such as a load resistor or a heater is provided that includes forming a dielectric layer onto a substrate, a target, or an adjacent functional layer, wherein the dielectric layer in one form defines a single layer of dielectric tape. The dielectric tape is laminated to the substrate, the target, or the adjacent functional layer through a single predetermined cycle of pressure, temperature and time, and then a resistive layer is formed on the dielectric layer, and a protective layer is formed over the resistive layer.
