Abstract
A novel, nozzle member for an inkjet print cartridge and method of forming the nozzle member are disclosed. In this method, the nozzles or orifices are formed in a flexible polymer tape by Excimer laser ablation. In one embodiment, a substrate containing heating elements is mounted on the back of the nozzle member. Conductors for providing electrical signals to the substrate are located inside the flexible polymer tape and end at a via overlying an associated electrode on the substrate. The via electrically connects the conductors to the associated electrode.
