ABSTRACT:
A method of producing an ink jet printhead with a plurality of nozzles and one or more heater elements corresponding to each nozzle. Each heater element is configured to heat a bubble forming liquid in the printhead to a temperature above its boiling point to form a gas bubble therein. The generation of the bubble causes the ejection of a drop of an ejectable liquid (such as ink) through the respective corresponding nozzle, to effect printing. Conveniently, a thin nozzle plate is formed in-situ on the wafer substrate. Depositing a nozzle plate by chemical vapor deposition (CVD) allows the nozzle plate to be included in the printhead at the scale of normal silicon wafer production, using processes normally used for semi-conductor manufacture. Standard lithographic equipment used in the modern semiconductor industry provides a high throughput as well as a high degree of accuracy.
