  • Patent number: 11521876
    Abstract: A horizontal substrate carrier is provided, for example a carrier for holding semiconductor substrates during horizontal thermal processing. The horizontal substrate carrier has asymmetrically placed support rails. One side of the horizontal substrate carrier has no upper rail while the other side of the horizontal substrate carrier has an upper rail placed at a relatively high location, for example at an angular location of 60° or more, more preferably of 70° or more, and most preferably at 90°. The side without an upper rail may be used for robotic loading of the horizontal substrate carrier. In a preferred embodiment, only three rails are provided: one upper rail on one side and two lower rails. The use and placement of these three rails can hold the substrate in precise uniform locations, minimize substrate movement, and minimize particle generation, all while allowing for easy robotic access.

  • Patent number: 6252351
    Abstract: A contact layer having a low resistance in an LED is extended from an inside edge of a light take-out region in a light emitting dot to a central position thereof, whereby an input current in the light take-out region expands, while an electrode is extended from an inside edge of the light take-out region to the center of the light take-out region so as to shape like substantially a letter T with a length which is not over the center, whereby increase in an electrode covering ratio in the light take-out region can be suppressed. As a result, a uniform light output in the light take-out region can be attained, so that a light output can be remarkably improved.

  • Patent number: 5384531
    Abstract: An apparatus for inspecting characteristics of semiconductor chips has a loading device for loading semiconductor chips onto a testing tray positioned by a servo motor, a CCD camera, an upper contact fixture controlled in X, Y, and .THETA. directions, and a lower contacting fixture driven by a cylinder. Positioning of the contact probe pins is accurately achieved by pattern processing and fully automated inspection is made possible. The apparatus is equipped with the same number of contact probe pins as the number of inspection points of a semiconductor chip; hence, all the cells of a semiconductor chip can be inspected as a unit. Therefore, the inspection can be made in a mode similar to practical conditions that occur after final assembly of the semiconductor chip.
