  • Publication number: 20220242124
    Abstract: A method of forming a print head, by forming a heater chip. Via zones having peripheries are defined on a substrate, with heaters formed along the entire peripheries of the via zones. Traces that electrically connect to each of the heaters are formed. In some embodiments, the heater chip is then stored for a period of time. After storing the heater chip, vias are formed in only a selected portion of the via zones, which is a subset of the via zones. A channel layer is formed on the heater chip by forming a first layer on the heater chip. Flow channels are formed in the first layer from the vias to only those heaters on the heater chip that are disposed along the selected portion of the via zones. Bubble chambers are formed in the first layer around only those heaters on the heater chip that are disposed along the selected portion of the via zones.
