Abstract
There is provided a method of improving the yield of a nozzle plate fabrication process, the method comprising determining a variation in the size of nozzles in a nozzle plate from a predetermined size or range of sizes for the nozzles, the nozzles in the nozzle plate having been fabricated using a plurality of mandrels, each mandrel defining a respective nozzle in the nozzle plate and determining modifications to the size of one or more mandrels in the plurality of mandrels to compensate for the determined variation in the size of nozzles in the nozzle plate. Also provided is a method of fabricating a nozzle plate, the method comprising fabricating a nozzle plate having a plurality of nozzles using a plurality of mandrels on a substrate, each mandrel defining a respective nozzle in the nozzle plate, the mandrels in the plurality of mandrels having varying sizes in order to compensate for local variations in the fabrication process that would result in local variations in the size of nozzles in the nozzle plate from a predetermined size or range of sizes.
