Abstract:
A high efficiency ink delivery printhead comprising:at least one resistor element positioned within said printhead for expelling ink on-demand therefrom, said resistor element being comprised of a doped polycrystalline silicon composition;at least one primary layer of electrically conductive material which is operatively connected to said resistor element, said primary layer being comprised of a metal silicide compound; andat least one additional layer of electrically conductive material positioned above said primary layer of electrically conductive material and being operatively attached thereto, said additional layer terminating at a position within said printhead which is spaced outwardly and apart from said resistor element in order to form a gap therebetween, said primary layer forming a conductive bridge within said gap between said additional layer and said resistor element.
