  • Patent number: 9486988
    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. A resistive layer is formed on the dielectric layer after the dielectric tape is laminated to the substrate. A protective layer is formed over the resistive layer.

  • Patent number: 8070899
    Abstract: A method of positioning a tape preform as a layer onto a resistive device substrate during the manufacture of a layered resistive device is provided. The method includes locating the tape preform in a predetermined position and translating one or more of the following relative to each other until a portion of the positioning device engages the tape preform: a positioning device, the resistive device substrate, and the tape preform. The method also includes continuing the translation until the tape preform engages the resistive device substrate and continuing the translation such that components of the positioning device progressively translate around the resistive device substrate and subsequently position the tape preform onto the resistive device substrate. In some forms, the method includes using a controller and/or applying a predetermined cycle of temperature, pressure, and time to the substrate and tape preform.
