PRINTHEAD INTEGRATED COMPRISING THROUGH-SILICON CONNECTORS

摘要

A printhead integrated circuit comprising a silicon substrate defining a frontside and a backside, inkjet nozzle assemblies positioned at the frontside, drive circuitry for supplying power to the inkjet nozzle assemblies and through-silicon connectors extending from the frontside towards the backside. The through-silicon connectors provides electrical connections between the drive circuitry and corresponding integrated circuit contacts. The integrated circuit contacts are positioned for connection to a backside-mounted connector film supplying power to the drive circuitry.
