摘要：
A method is provided for manufacturing a printer nozzle. The method includes the step of depositing a metal layer upon a semi-conductor wafer. The metal layer defines a pair of protruding portions which each form a respective electrical contact. The method further includes the step of etching the metal layer through to the wafer to form a nozzle region and to electrically isolate the electrical contacts. In one embodiment, the nozzle region is defined by a circular wall.
