  • Patent number: 11498831
    Abstract: A packaged micro-electro-mechanical system (MEMS) device (100) comprises a circuitry chip (101) attached to the pad (110) of a substrate with leads (111), and a MEMS (150) vertically attached to the chip surface by a layer (140) of low modulus silicone compound. On the chip surface, the MEMS device is surrounded by a polyimide ring (130) with a surface phobic to silicone compounds. A dome-shaped glob (160) of cured low modulus silicone material covers the MEMS and the MEMS terminal bonding wire spans (180); the glob is restricted to the chip surface area inside the polyimide ring and has a surface non-adhesive to epoxy-based molding compounds. A package (190) of polymeric molding compound encapsulates the vertical assembly of the glob embedding the MEMS, the circuitry chip, and portions of the substrate; the molding compound is non-adhering to the glob surface yet adhering to all other surfaces.

  • Publication number: 20060274124
    Abstract: A thermal inkjet printhead 100 of the present invention includes a heating element 110, an ink chamber, control circuitry 108, an ink reservoir, and a memory array 106. The control circuitry 108 causes the heating element to generate thermal energy thereby causing ink within the ink chamber to generate bubbles of ink, which are then expelled through a nozzle. The ink reservoir replenishes used ink in the ink chamber. The memory array 106 stores and provides the identification parameters for the thermal inkjet printhead 100. The identification parameters are typically provided during initialization of the printer and include color(s) of ink (e.g., black, green, red, blue), a number of nozzles on the thermal inkjet printhead, an addressing frequency, nozzle spacing, heating architecture, and the like.
