An ink jet printhead fabrication process produces a plurality of printheads from two mated substrates (31,36) by two dicing operations. One dicing operation produces the nozzle face (29) for each of a plurality of printheads and optionally produces the nozzles (27). This dicing blade, together with specific operating parameters, prevent the nozzles from chipping and the nozzle faces from scratches and abrasions. A second dicing operation with a dicing blade severs the mated substrates into separate printheads. The dicing operation which produces the nozzle face is preferably conducted in two steps. A first cut makes the nozzle face, but does not sever the two mated substrates. A second dicing cut severs the two substrates, but does so in a manner that prevents contact by the dicing blade with the nozzle face. |
