摘要： A micro-fluid ejection head has a resistor layer defining a heater element. An insulative layer underlies the heater element and a capping layer on the insulative layer substantially prevents ion mobility between the resistor and insulative layers. Resistance stability of the heater has been shown improved as has adhesion of the heater to the insulator. Representative layers include insulation of methyl silesquioxane (MSQ) in a thickness of about 5000 Angstroms or more, while the cap is a silicon nitride in a thickness of about 2000 Angstroms or less. Other capping layers include silicon carbide, silicon oxide or dielectrics. The resistor layer typifies TaAlN in a thickness of about 350 Angstroms, including overlying anode and cathode conductors that define the heater. Coating layers are also disclosed as are thermal barrier layers.

摘要： An ink composition for used in an inkjet printer is provided. The ink composition includes a carrier medium, a colorant, and a silicon doping agent. The silicon doping agent may include silicic acid, silicon dioxide, or silicates. This silicon-doped ink reduces and prevents the etching of the silicon based components of the printhead. Silicon-doped inks protect the printhead from damage, thus improving printhead reliability and increasing printhead service life.

摘要： A piezoelectric inkjet printhead is monolithically fabricated on a substrate. The printhead includes a plurality of cavities formed into the substrate, piezoelectric actuators disposed over the top of the cavities, a fluidic structure and an ink supply channel. The piezoelectric actuators are formed over the cavities using a sacrificial material which fills the cavities and is removed after the actuators are formed. The fluidic structure defines pressurizing chambers and channels connected to the ink supply channel. The fluidic structure has a plurality of nozzle holes formed on the top surface. The cavities are connected to either a venting channel formed from the backside of the substrate or a venting chamber formed inside the fluidic structures.
