摘要： This invention relates to a printhead substrate capable of suppressing an increase in wiring width and an increase in the size of a substrate formed by a film forming process while increasing the number of simultaneously driven printing elements in order to improve the printing performance, a printhead using the substrate, and a printing apparatus using the printhead. The wiring lines of the substrate are formed into a common wiring line, and energy applied to a heating resistance element is prevented from deviating from a stable ink discharge range owing to the difference in the number of simultaneously driven heating resistance elements. For this purpose, a driving element is greatly downsized in comparison with a conventional one, and the operation region of a MOS transistor is shifted from the non-saturation region to the saturation region.

摘要： A substrate is formed for use of an ink jet recording head provided with a plurality in heat generating members for generating thermal energy to be utilized for discharging ink, an interlayer film arranged for the lower layer of each of said heat generating members, and a protection layer for protecting said heat generating member. Each of the heat generating members of the substrate is structured by metal and insulator, and at the same time, the rate of metal content in the vicinity of the interfaces of the heat generating member becomes smaller than that in the center of the heat generating member in the film thickness direction thereof. With the structure of such member thus arranged, it is made possible to prevent or suppress interlayer peelings and cracks from taking place in each of the heat generating resistive layers where temperature changes are made intensely due to thermal cycle.
