    Abstract: A single silicon wafer micromachined thermal conduction sensor is described. The sensor consists of a heat transfer cavity with a flat bottom and an arbitrary plane shape, which is created in a silicon substrate. A heated resistor with a temperature dependence resistance is deposed on a thin film bridge, which is the top of the cavity. A heat sink is the flat bottom of the cavity and parallel to the bridge completely. The heat transfer from the heated resistor to the heat sink is modulated by the change of the thermal conductivity of the gas or gas mixture filled in the cavity. This change can be measured to determine the composition concentration of the gas mixture or the pressure of the air in a vacuum system.

    Abstract: A packaged device includes a first die, a second die, and specially spaced and positioned sets of package terminals. The first die includes a pulse-width modulator (PWM), a processor, a timer, high-side drivers, low-side drivers, and a fault protection circuit. The second die includes ultra-high voltage high-side drivers. In an ultra-high voltage application, the PWM and external circuitry together form a switching power supply that generates a high voltage. The high voltage powers external high-side transistors. The processor and timer control the ultra-high voltage high-side drivers, that in turn supply drive signals to the external high-side transistors through the package terminals. External low-side transistors are driven directly by low-side drivers of the first die. If the fault protection circuit detects an excessive current, then the fault protection circuit supplies a disable signal to high-side and low-side drivers of both dice.

  • Patent number: 8709850
    Abstract: The invention relates to a method for production of at least one thermoelectric apparatus with the steps of: preparation of a first wafer (1) which is formed from a thermoelectric material of a first conductivity type; preparation of a second wafer which is formed from a thermoelectric material of a second conductivity type; structuring of the first wafer (1) so that a group of first thermoelectric structures (7) is produced; structuring of the second wafer so that a group of second thermoelectric structures is produced; and linking of the first to the second wafer in such a manner that the first and the second thermoelectric structures are electrically connected together and thus form the thermoelectric apparatus. According to the invention, before the structuring of the first wafer (1), a first contact material (3) is deposited on the first wafer (1) and/or before the structuring of the second wafer, a second contact material is deposited onto the second wafer.

  • Patent number: 8710859
    Abstract: Disclosed is a method for testing multi-chip stacked packages. Initially, one or more substrate-less chip cubes are provided, each consisting of a plurality of chips such as chips stacked together having vertically connected with TSV's where there is a stacked gap between two adjacent chips. Next, the substrate-less chip cubes are adhered onto an adhesive tape where the adhesive tape is attached inside an opening of a tape carrier. Then, a filling encapsulant is formed on the adhesive tape to completely fill the chip stacked gaps. Next, the tape carrier is fixed on a wafer testing carrier in a manner to allow the substrate-less chip cubes to be loaded into a wafer tester without releasing from the adhesive tape. Accordingly, the probers of the wafer tester can be utilized to probe testing electrodes of the substrate-less chip cubes so that it is easy to integrate this testing method in TSV fabrication processes.

  • Patent number: 8664602
    Abstract: An apparatus and method for a wafer level vacuum package uncooled microbolometer focal plane array (FPA) on a wafer level substrate with a thin film getter-reflector (G-R). The G-R removes gas from the vacuum package and is reflective in the frequency band of the FPA. Sensor pixels are supported about a quarter-wavelength above the G-R which is within the perimeter of the imaging array. The package is evacuated through a single aperture, and vacuum is maintained for the lifetime of the FPA. Imaging sensor size is reduced while maintaining resolution by reducing non-imaging area.
