摘要：
A printhead integrated circuit includes: a plurality of nozzle chambers disposed on a substrate; a heater element positioned in each nozzle chamber; drive circuitry for supply power to each heater element; and a plurality of ink supply channels defined in the substrate for supplying fluid to the nozzle chambers. Each heater element consists of solid material having a mass of less than 10 nanograms. In use, the solid material is heated to cause formation of a gas bubble inside each nozzle chamber.
