Abstract
A metallic resistive heater and a method of production are described. The resistive heater has a metallic component that is electrically conductive (i.e. has low resistivity) and an oxide, nitride, carbide, and or boride derivative of the metallic component that is electrically insulating (i.e., has high resistivity). The resistivity is controlled by controlling the amount of oxide, nitride, carbide, and boride formation during the deposition of the metallic component and the derivative.
