More Information
Summary:The invention provides improved methods for making ink jet printer nozzle plates and to nozzle plates made by the method. In the method, a polymeric film having a polymeric layer, an adhesive layer and a protective layer over the adhesive layer is ablated in order to produce flow features comprising ink flow channels (16), firing chambers (14), nozzle holes (18) and an ink supply region (24). Once the flow features are formed, the protective layer is removed from the polymeric film so that the nozzle plate can be attached to a semiconductor substrate. In the method a portion (26) of the polymeric material in the ink supply region (24) remains substantially unablated in order to reduce the debris produced during the ablation step. By reducing the amount of debris, removal of the protective layer after ablation is enhanced.
