ABSTRACT:
An electro-thermal transducer is composed of a substrate, a resistive heater element formed on the substrate, and electrically conductive members to supply electric power to the resistive heater element, wherein the resistive heater element contains a metal boride as the principal constituent. The transducer of this construction is capable of selecting its resistivity to a high value and causing a large electric current to flow in the form of short pulses for the purpose of high speed printing, hence it is stable against repetitive pulse applications over a long period of time. The method of producing the transducer is by forming a layer of a resistive heater element including a metal boride on a substrate of an electrically insulative material by conducting a reactive sputtering reaction between a target of an elemental form of the metal and diborane gas; and then applying to the resistive heater element an electrically conductive member for supplying the resistive heater element with electric power.
