Method of using photolithography and etching for forming a nozzle plate of an inkjet print head
摘要:
A method of forming a nozzle plate of an inkjet print head. A silicon chip is provided with an activated device and a first film is formed on the silicon chip, with a first opening corresponding to the activated device. Then, a second film is formed on the first film. Next, a photoresist layer is formed on the second film, such that the photoresist layer has a second opening corresponding to the first opening. Next, the second film under the second opening of the photoresist layer is etched to form a via in the second film passing through the first opening.
