A high efficiency thermal inkjet printhead (80, 196) which uses a novel resistor system. The printhead (80, 196) includes a support structure (202, 208), at least one layer of material (104) which comprises at least one opening (108) therethrough, and at least one ink expulsion resistor (86) located within the printhead (80, 196) between the support structure (202, 208) and the layer of material (104) having the opening (108) therein. The resistor (86) is produced from at least one metal silicon oxynitride composition. Numerous benefits are achieved by this development including (A) reduced resistor (86) current consumption and greater energy efficiency; (B) increased bulk resistivity of the resistor elements (86) compared with prior systems; (C) cooler printhead (80, 196) operation; (D) multiple economic benefits including the ability to use less-costly, high voltage/low current power supplies; and (E) improved reliability, stability, and longevity levels in connection with the printhead (80, 196) and resistor elements (86). <IMAGE> |
