Abstract
A method of manufacturing a layered heater includes: applying a dielectric material on a substrate to form a dielectric layer; thermal-spraying a resistive material on the dielectric layer to form a resistive layer on the dielectric layer; forming a plurality of conductive overlays at predetermined locations on the substrate; and forming a plurality of cuts into the resistive layer by laser cutting to form a resistive circuit pattern that overlaps the conductive overlays.
