Abstract: The present invention relates to the design, construction and manufacture of a novel electrical high temperature heater having a polymer thick film conductor paste with which to form an electrode on resistive film.

Abstract: A conductive paste composition contains a source of an electrically conductive metal, a fusible material, a synthetic clay additive, and an optional etchant additive, dispersed in an organic medium. An article such as a photovoltaic cell is formed by a process having the steps of deposition of the paste composition on a semiconductor substrate by a process such as screen printing and firing the paste to remove the organic medium and sinter the metal and fusible material. The synthetic clay additive aids in establishing a low resistance electrical contact between the front side metallization and underlying semiconductor substrate during firing.

Abstract: The invention is directed to a process and more particularly, to utilizing polymer solutions to make thick film compositions. In one embodiment the process is directed to the formation of photoimageable thick film compositions for use in photo-patterning methods to make photoimageable electrodes in flat panel display applications, including plasma display panels (PDP). Polymer solutions are obtained by directly polymerizing desired monomers in a desired solvent to form a desired polymer, rather than by dissolving a pre-made polymer in a desired solvent. Other ingredients are added to the polymer solution to directly form thick film pastes, including photoimageable thick film pastes.

Abstract: The invention is directed to a magnetic thick film composition comprising particles of permanent magnetic materials dispersed in organic medium wherein the medium comprises a polymer selected from polyurethane, phenoxy and mixtures thereof, and organic solvent.
