Manufacturing inkjet printheads with large numbers of nozzles
First Claim
1. A method of fabricating an inkjet printhead having an array of inkjet nozzle arrangements, said method comprising the steps of:
- defining a single nozzle arrangement;
replicating the single nozzle arrangement at least once to define a pod of nozzles which are for the ejection of ink of one color;
replicating the pod at least once to define a podgroup;
replicating the podgroup at least once to define a segment of the printhead;
replicating the segment at least once to define and form the printhead; and
fabricating the inkjet nozzle arrangements with an integrated circuit fabrication technique carried out on a substrate;
wherein each nozzle arrangement is fabricated to incorporate CMOS drive circuitry and a micro electromechanical system connected to the CMOS drive circuitry to be actuated by the CMOS drive circuitry to displace in least one component of the micro electromechanical system relative to the substrate.

Abstract
A method of construction of an inkjet printhead having a large array of inkjet nozzle arrangements by defining a single inkjet nozzle arrangement for the ejection of ink from a single nozzle and utilizing a series of translations and rotations of the single inkjet nozzle arrangement to define all the inkjet nozzles of the inkjet print head. The utilizing step can comprise: initially forming those nozzles in a pod; forming a group of pods corresponding to each color utilized in the print head; forming a firing group of pods; forming a segment of the printhead; forming each segment of the print head. The inkjet nozzle arrangements can include a series of layers deposited and etch utilizing a mask.
