    摘要： A plurality of ink jet printheads are produced from two aligned and bonded substrates by an improved fabrication method. The confronting surface of one of the substrates contains a plurality of linear arrays of heating elements and driver circuitry, and the confronting surface of the other substrate contains a plurality of sets of shallow channel recesses, reservoir recesses, and alignment openings. Prior to mating of the substrates, the substrate surface having the channel recesses is coated with a layer of thermosetting adhesive, and a thick film layer is deposited on the substrate surface having the heating elements and driver circuitry and patterned to provide a plurality of vias therein at predetermined locations. The vias expose the heating elements, provide ink bypass trenches, and provide a number of groupings of small pits. In one embodiment, the alignment openings are used to visually align and mate the substrates, so that each alignment opening is aligned with a respective one of the groups of small pits in the thick film layer. To prevent misalignment between the substrates before the adhesive layer is cured, a UV curable adhesive is inserted into the alignment openings and into each group of small pits in the thick film layer aligned therewith and cured, thus fastening the substrates together. The fastened substrates are placed in a curing oven without lost of alignment therebetween and the thermosetting adhesive is cured. The bonded substrates are then diced into a plurality of individual printheads.

    摘要： A method of fabricating thermal ink jet printheads comprises aligning and bonding a pair of silicon wafers together, which have, on opposing confronting surface thereof, a plurality of sets of linear arrays of heating elements and associated driver circuitry on one wafer surface and a plurality of sets of parallel grooves and a communicating reservoir for each set of grooves. The grooves and reservoirs are filled with a filler material which is solid or gels at room temperature and liquid at higher temperatures. The bonded pair of wafers are severed into a plurality of individual printhead sby dicing processes conducted at room temperature. One of the dicing processes cuts the grooves in a direction perpendicular thereto in order to form concurrently the nozzle face and nozzles. The solid filler material supports fragile edges of the wafers and prevents entry of dicing debris and other contaminants. The printheads are subjected to heat, spinning, and high pressure water spray to remove the filler material.
