Patent abstract
A method of manufacturing a printhead for an inkjet print cartridge includes depositing a metal film on a mandrel; separating the metal film from the mandrel, mounting the metal film to a work holder, modifying the metal film while the metal film remains mounted on the work holder, laminating the metal film to a barrier material and semiconductor substrate to form a printhead, and applying heat to the printhead such that the printhead barrier layer is cured and the metal film is bonded thereto. Laminating the metal film to the barrier material includes preheating the barrier material and placing the metal film on the preheated barrier material.
