摘要:A method of fabricating a printhead integrated circuit configured for backsideelectrical connections. The method comprises the steps of: (a) providing a wafercomprising a plurality of partially-fabricated nozzle assemblies on a frontside of thewafer and through-silicon connectors extending from the frontside towards a backside ofthe wafer; (b) depositing a conductive layer on the frontside of said wafer and etching toform an actuator for each nozzle assembly and a frontside contact pad over a head ofeach through-silicon connector; (c) performing further MEMS processing steps to
complete formation of nozzle assemblies ink supply channels through-silicon connectors;and (d) dividing the wafer into individual printhead integrated circuits. Each printheadintegrated circuit thus formed is configured for backside-connection to the drive circuitryvia the through-silicon connectors the contact pads.
