ABSTRACT:
A method of fabricating an inkjet nozzle assembly having a seal member bridging between a moving portion and a stationary portion. The method includes the steps of: (a) providing a partially-fabricated printhead comprising a nozzle chamber sealed with a roof, (b) etching a via through the roof to define the moving portion on a first side of the via and the stationary portion on a second side of the via; (c) plugging the via with a plug of sacrificial material; (d) depositing a layer of flexible material over the plug; and (e) removing the plug to provide the inkjet nozzle assembly. The resultant seal member is comprised of the flexible material.
