Abstract:
1. A method, comprising the steps of: depositing a layer of a sacrificial material above a substrate in a first region of the substrate, separate from a second region of the substrate, wherein the first region of the substrate includes an inkjet nozzle, and a corrosion resistant film is to be provided above the second region; depositing the corrosion resistant film over the sacrificial material and the second region simultaneously, so that a first portion of the corrosion resistant film overlies the sacrificial material in the first region, and a second portion of the corrosion resistant film overlies the second region; removing the first portion of the corrosion resistant film by chemical mechanical polishing, so that the second portion of the corrosion resistant film forms a heater for the inkjet nozzle; and removing the sacrificial material from the first region using an etching process that selectively etches the sacrificial material, but not the corrosion resistant film.
