  • INK JET PRINTHEAD DEVICE WITH COMPRESSIVE STRESSED DIELECTRIC LAYER
    Publication number: 20140340450
    Abstract: An ink jet printhead device includes a substrate and at least one first dielectric layer above the substrate. A resistive layer is above the at least one first dielectric layer. An electrode layer is above the resistive layer and defines first and second electrodes coupled to the resistive layer. At least one second dielectric layer is above the electrode layer and contacts the resistive layer through the at least one opening. The at least one second dielectric layer has a compressive stress magnitude of at least 340 MPa.
