Patent ID: 7721441

Claim:
A method of fabricating a film for attachment of one or more printhead integrated circuits to an ink supply manifold, said method comprising the steps of: (a) providing an adhesive polymeric film having at least one protective liner; (b) depositing photoresist onto the protective liner; (c) photopatterning said photoresist to define a plurality of openings positioned for etching supply holes through said adhesive polymeric film; (d) etching the plurality of ink supply holes through said protective liner and said adhesive polymeric film, said photoresist on said protective liner acting as a mask for said etch; and (e) removing the protective liner from said adhesive polymeric film, including said photoresist, after said etching step is complete, thereby providing said adhesive polymeric film for attachment of one or more printhead integrated circuits to an ink supply manifold.
