摘要： The present invention includes as one embodiment an ink jet printhead having a circuit with plural resistors and a power bus. The printhead includes a metal stack formed within the circuit, which is comprised of a first metal layer and a second metal layer and at least one power via. The power via is formed within the circuit as an interface between the first metal layer and the second metal layer and acts as a separation barrier between conductive portions of the resistors and the power bus.

摘要： A firing chamber configuration for the drop ejectors of inkjet printheads extends the life of the heat transducer by ensuring that bubble collapse (and attendant cavitation) occurs at a location well spaced from the heat transducer. The sidewalls of the firing chamber are shaped relative to the firing chamber entry in a manner such that a strong jet of inflow ink is provided for moving the collapsing vapor bubble from the center of the chamber and against a curved back wall of the firing chamber. In one preferred embodiment, the refill ink impinges on the back wall, divides, and is redirected away from the back wall toward pockets defined in chamber. The pockets are remote from the heat transducer. As a result, the refill ink urges the collapsing (bifurcated) bubble into the pockets where final collapse occurs away from the heat transducer.

摘要： Methods for fabricating a printhead are described. In one embodiment, a method includes forming on a substrate using a single fabrication technique multiple resistors, some of the resistors to be used as heater resistors configured to eject fluid and some of the resistors to be used as storage resistors that store data, annealing the heater resistors, and intentionally not annealing at least one of the storage resistors, wherein the annealed storage resistors have a first state representing a first digital value and the unannealed storage resistors have a second state representing a second digital value, such that the values associated with the storage resistors can be read by an appropriate detection circuit.
