摘要： Disclosed is an improved thermal ink jet print head with an amorphous diffusion barrier that inhibits corrosion associated with ink. The head has a silicon substrate, a silicon dioxide insulating layer, a tantalum aluminum alloy (TaAl) resistive layer, and two separated gold conductive regions formed over the resistive layer. Ink is drawn into a channel bounded above by an orifice plate and below by the TaAl exposed between the two separated gold regions. The ink is superheated and expelled as fine droplets through the orifice plate. The invention minimizes corrosion by placing a thin corrosion-resistant layer of amorphous metallic alloy over the conductive layer, thereby improving durability of the print head.

摘要： A thermal ink jet head incorporates bubble-generating resistors, each with a relatively thick layer of unpassivated resistive material, such as TaAl. The thermal ink jet head includes an ink source, ink channels, respective orifices, and circuitry for providing the electrical energy which the resistors convert to heat to form bubbles which expel ink through respective orifices. A range between 3,000 .ANG. and 5,000 .ANG. is preferred for the resistive material to minimize failure rate while avoiding thermal, electrical and manufacturing limitations of passivated resistors.

摘要： A system for delivering ink to print heads in thermal ink jet printers includes a liquid compartment with a gas space thereabove at sub-atmospheric pressure, a hydrophobic membrane mounted between the liquid compartment and the surrounding environment for allowing ambient gases to bubble into the liquid while preventing liquid from flowing in the opposite direction through the membrane, at least one chamber that provides a reservoir of ink with a gas space thereabove at sub-atmospheric pressure, and a manifold connecting the gas space in the liquid compartment with the gas space in the ink chamber. Thermal ink jet print heads are mounted in ink-flow communication with the ink chamber and are adapted for ejecting ink onto sheets to be printed. In operation, ink flows into the thermal ink jet print heads at a flow rate which is regulated by a generally constant back pressure. This novel pen body construction enables the hydrophobic membrane to be completely isolated from the ink in the multiple ink reservoirs of the pen, with the advantage that ingredients and additives within the ink do not degrade the surface properties of the hydrophobic membrane material.

摘要： The edge profile of a silicon layer is shaped to have a gradual incline considerably less than 90.degree. by continuously reducing the amount of oxygen mixed with carbon tetrachloride in a reactive ion etching environment. The etching mode varies from complete isotropic etching when the amount of oxygen is maximum, to complete anisotropic etching when the oxygen content is zero.
