    Abstract: A wafer processing system according to one embodiment includes a chamber housing having an exhaust and a rotatable wafer support member for supporting a wafer. A filter fan unit is contained internally within the chamber housing and includes a variable speed fan. A controller is in communication with the variable speed fan to allow the housing to be maintained at either a net positive pressure or a net negative pressure relative to a surrounding environment (e.g., the clean room) outside the housing and also the relative pressures of the chamber housing, the surrounding environment and a handler area can be monitored and controlled.

  • Patent number: 9694436
    Abstract: The use of lead-free solder (flux) in Wafer Level Packaging applications requires more control of the temperature and environment during the reflow process. The flux needs to be applied by spin coating, reflowed in a controlled environment and then removed with a cleaning process. Incorporating these three processes in one compact system provides an efficient and economical solution. The unique design of the reflow oven consists of multiple hotplates and one cold plate, arranged in a circle to allow wafers to proceed through the oven in a rotary fashion.

  • Patent number: 9333446
    Abstract: An apparatus for filtering dry film solvent includes a hollow vessel having a side wall, an open top end and a second end that includes a main outlet that allows fluid to flow out of a hollow interior of the vessel. A removable cover closes off the open top end of the vessel. The apparatus also includes at least one fluid inlet port formed along the side wall of the vessel and defining an entrance into the hollow interior of the vessel and at least one fluid outlet port formed along the side wall of the vessel and defining an exit from the hollow interior of the vessel. A removable filter member is disposed within the hollow interior and is defined by a frame and filter media that extends across the frame such fluid flowing into the hollow interior through the main inlet must flow through the filter media to reach the main outlet. The filter media is disposed at an angle other than 90 degrees relative to the frame of the filter member.

  • Patent number: 9250328
    Abstract: A graphics-aided geodesic device is provided. The device may include a display, camera, distance meter, GNSS (Global Navigation Satellite System, including GPS, GLONASS, and Galileo) receiver and antenna, and horizon sensors. Data from the camera and horizon sensors may be displayed to assist the user in positioning the device over a point of interest. In one example, the distance meter may be used to determine the position of the point of interest. In another example, images of the point of interest taken from multiple locations may be used to determine the position of the point of interest.

  • Patent number: 7959891
    Abstract: The present invention provides a process for obtaining fullerene-like metal chalcogenide nanoparticles, comprising feeding a metal precursor selected from metal halide, metal carbonyl, organo-metallic compound and metal oxyhalide vapor into a reaction chamber towards a reaction zone to interact with a flow of at least one chalcogen material in gas phase, the temperature conditions in said reaction zone being such to enable the formation of the fullerene-like metal chalcogenide nanoparticles product. The present invention further provides novel IF metal chalcogenides nanoparticles with spherical shape and optionally having a very small or no hollow core exhibiting excellent tribological behaviour. The present invention further provides an apparatus for preparing various IF nanostructures.

  • Publication number: 20080170984
    Abstract: The present invention provides a process for obtaining fullerene-like metal chalcogenide nanospheres, comprising: (a) feeding a metal halide, metal carbonyl, organo-metallic compound or metal oxyhalide vapor into a reacting chamber towards a reacting zone to interact with a flow of at least one chalcogen material in gas phase, the temperature conditions in said reacting zone being such enabling the immediate formation of spherical nucleation seeds of the product; (b) controllably varying the flow of said metal halide, metal carbonyl, organo-metallic compound or metal oxyhalide vapor into said reacting chamber thereby controlling the amount, morphology and size of the so-produced nanospheres, to obtain substantially non-hollow fullerene-like metal calcogenide nanospheres in solid form. The present invention further provides novel IF metal chalcogenides with substantially non-hollow, spherical shape, and having excellent tribological behaviour.
