The heater chip is a semiconductor substrate having a resistive layer deposited on the substrate, a dielectric layer deposited on the resistive layer, a cavitation layer for contact with ink, and an adhesion layer between the dielectric layer and cavitation layer. The adhesion layer is selected from the group consisting of tantalum nitride (TaN), tantalum oxide (TaO), silicon nitride (SiN), and titanium nitride (TiN), provided the adhesion layer and cavitation layer are selected so that the adhesion layer has no elemental component in common with the cavitation layer when the dielectric layer is comprised of SiC/SiN. Adhesion between the dielectric layer and cavitation layer is significantly enhanced by the invention.

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.

    摘要: A heater stack includes first strata configured to support and form a fluid heater element responsive to repetitive electrical activation and deactivation to produce cycles of fluid ejection and second strata overlying the first strata to protect the heater element. A decomposed sacrificial layer of a preselected polymer between the substrate and a heater substrata containing the heater element provides a decoupled relationship between them which, during a heat-up period of each cycle, results in the heater element buckling out of physical contact with substrate enabling the heater element to transfer heat energy for producing fluid ejection into the fluid without transferring any into the substrate whereas the decoupled relationship, during the next following cool-down period of each cycle, results in the heater element de-buckling back into physical contact with the substrate enabling the heater element transfer residual heat energy to the substrate.

    摘要: A heater stack includes first strata configured to support and form a fluid heater element responsive to repetitive electrical activation and deactivation to produce repetitive cycles of fluid ejection from an ejection chamber above the heater element and second strata overlying the first strata and contiguous with the ejection chamber to protect the heater element.
