摘要:
Disclosed is a process for forming a channel wafer for a novel ink jet printhead, having an ink particle-filter layer over the ink-inlet surface thereof. The process comprises the steps of applying a thin coating of a heat-curable, photopatternable polymer composition to an intermediate substrate having a release surface and drying the coating to form a semi-solid adhesive layer. The layer and supporting substrate are pressed against the ink-inlet surface of a channel wafer with an optional adhesive layer to bond the layer to the ink inlet surface. The substrate is separated to transfer the contacting area of the semi-solid layer to the ink-inlet surface as a laminate, and the semi-solid layer is exposed through a filter-forming mask and ink particle-filter openings are developed therethrough, either before or after transfer of the semi-solid adhesive layer from the intermediate substrate to the ink-inlet surface of the channel wafer, and the filter layer is cured.
