  • Patent number: 10048148
    Abstract: A process for manufacturing a MEMS pressure sensor having a micromechanical structure envisages: providing a wafer having a substrate of semiconductor material and a top surface; forming a buried cavity entirely contained within the substrate and separated from the top surface by a membrane suspended above the buried cavity; forming a fluidic-communication access for fluidic communication of the membrane with an external environment, set at a pressure the value of which has to be determined; forming, suspended above the membrane, a plate region made of conductive material, separated from the membrane by an empty space; and forming electrical-contact elements for electrical connection of the membrane and of the plate region, which are designed to form the plates of a sensing capacitor, the value of capacitance of which is indicative of the value of pressure to be detected. A corresponding MEMS pressure sensor having the micromechanical structure is moreover described.

  • Patent number: 9975756
    Abstract: A micro-electro-mechanical pressure sensor device, formed by a cap region and by a sensor region of semiconductor material. An air gap extends between the sensor region and the cap region; a buried cavity extends underneath the air gap, in the sensor region, and delimits a membrane at the bottom. A through trench extends within the sensor region and laterally delimits a sensitive portion housing the membrane, a supporting portion, and a spring portion, the spring portion connecting the sensitive portion to the supporting portion. A channel extends within the spring portion and connects the buried cavity to a face of the second region. The first air gap is fluidically connected to the outside of the device, and the buried cavity is isolated from the outside via a sealing region arranged between the sensor region and the cap region.

    Abstract: Lighting devices, and methods of manufacturing the same, are provided. A lighting device includes a cover through which emitted light passes and a formed flexible light engine. The formed flexible light engine is placed within a housing, or serves as the housing itself. An interface couples to cover to the housing or the formed flexible light engine. The formed flexible light engine includes a flexible substrate and a plurality of solid state light sources located thereon. The plurality of solid state light sources are configured to emit light through the cover. The formed light engine has a defined shape created during the forming process. This enables placement on the housing within the lighting device, or contributes to the overall shape of the lighting device.
