    摘要： A method of fabricating a bridge beam of an inkjet printhead employs a cavity formed under the bridge beam and an etch-stop layer that limits a back-surface recess formation. The method includes forming a cavity that connects between a bottom of a pair of trenches in and extending from a front surface of a substrate and depositing an etch-stop layer at a bottom of the cavity. The method further includes forming a recess in a back surface of the substrate, the recess exposing the etch-stop layer and the etch-stop layer limiting a depth of the formed recess. The method further includes removing the exposed etch-stop layer to connect the cavity and the recess, the bridge beam being a portion of the substrate above the formed cavity and between the trenches.

    摘要： A method and apparatus for assembling an inkjet printhead is disclosed. The apparatus comprises one or more microheater resistors and a material, which can be reflowed by use of the heat generated by the microheater, disposed proximate to the heater resistor. The microheater resistor comprises a heater resistor with an input port and an output port. A first electrical conductor, coupled to the input port of the heater resistor, receives a first voltage and a second electrical conductor, coupled to the output port of the heater resistor, receives a second voltage. A curing effect in the adhesive is produced by heat generated in the heater resistor when electrical current flows through the resistor in response to an application of a first voltage to the first electrical conductor and a second voltage to the second electrical conductor.

    摘要： Precision alignment of one or more parts on a common carrier is described. A self-aligned common carrier includes a carrier substrate having one or more pockets formed in the substrate. Each pocket includes a side profile formed in the pocket. A chip having an identical side profile that complements the side profile in the pocket is mounted to the carrier substrate by inserting the chip into the pocket. The complementary side profiles result in near perfect self-alignment between the chip and at least two orthogonal planes of the carrier substrate. The chip and the carrier substrate can be made from a single crystal semiconductor material and the side profiles can be formed by anisotropic etch process that selectively etches the chip and the substrate along a predetermined crystalline plane. The chip and the carrier substrate can be single crystal silicon having a (100) crystalline orientation and the side profiles can be formed by selectively etching the silicon along a (111) crystalline plane. The matching coefficients of thermal expansion between the chip and the carrier substrate substantially reduces thermal stress related interconnect failures and misalignment between the chip and the carrier substrate. The carrier substrate and the chip can be anodically bonded to each other by oxidizing either one of the carrier substrate and the chip and etching the side profiles so that they are atomically flat.
