  • Patent number: 11977099
    Abstract: A method for manufacturing a semiconductor device in which probes and the layout of the electrode pads of a test element group (TEG) are associated is provided. As a semiconductor device is miniaturized, a scribe area on a wafer also tends to decrease. Accordingly, it is necessary to reduce the size of a TEG arranged in the scribe area, and efficiently arrange an electrode pad for probe contact. Thus, it is necessary to associate the probes and the layout of the electrode pad. According to the method, a layout of a TEG electrode pad corresponding to a plurality of probes arranged in a fan shape or probes manufactured by Micro Electro Mechanical Systems (MEMS) technology is provided.

  • Patent number: 5135385
    Abstract: A clamping system includes a fixed platen fixed to one end of a machine base and a plurality of clamping cylinders, the fixed platen holding a fixed mold therein, a movable platen fixed to the other end of the machine base and holding a movable mold therein, a plurality of tie bars extending through the movable platen and including pistons at their one ends, the pistons being slidably received within the clamping cylinders, and screw threads or grooves substantially at their longitudinal center, a unit disposed between the movable platen and the fixed platen and operable to move the movable platen to and from the fixed platen, two-part nuts mounted to the movable platen and meshingly engageable with the screw threads or grooves of the tie bars, and stoppers each of which is engaged with a recess provided on each of the tie bars mounted to the movable platen on the side opposite to the fixed platen characterized in that screws are threaded at end portions of the tie bars on the side of the fixed platen, screws

  • Patent number: 4527507
    Abstract: A spray apparatus is disclosed which is capable of producing a sharp-edged layer of coating in overlap over the surfaces coated in a different color so as to provide a distinctly divided two-tone pattern of wide dimensions without using masking tape. The spray apparatus comprises a first spray means and at least one second spray means different in nozzle design from the first spray means. In the first spray means, a film of coating is produced by an airless type paint discharge nozzle discharging a spray of atomized paint under pressure in an otherwise conical shape which is to be altered in spray formation by a jet of pressurized air whose axis is offset from the axis of the spray of paint and this film is thick enough along one edge and in the center while decreasing in coating toward the opposite edge.
