  • Patent number: 7091733
    Abstract: A reliability evaluation test apparatus of this invention includes a wafer storage section which stores a wafer in a state wherein the electrode pads of a number of devices formed on the wafer and the bumps of a contactor are totally in electrical contact with each other. The wafer storage section transmits/receives a test signal to/from a measurement section and has a hermetic and heat insulating structure. The wafer storage section has a pressure mechanism which presses the contactor and a heating mechanism which directly heats the wafer totally in contact with the contactor to a predetermined high temperature. The reliability of an interconnection film and insulating film formed on the semiconductor wafer are evaluated under an accelerated condition.

  • Publication number: 20050206396
    Abstract: In a vacuum prober, a head plate is arranged on a prober chamber. A stage, first moving mechanism, recessed chamber, and sealing member are provided in the prober chamber. The stage is arranged below a probe card. The first moving mechanism vertically moves the stage in at least the Z direction. The recessed chamber has a bottom portion and side portion. A lower camera, an upper camera, and the stage are operated to obtain data for alignment. When the upper end of the side portion of the recessed chamber comes into tight contact with the lower surface of the sealing member and a vacuum mechanism evacuates the recessed chamber, a vacuum chamber is formed. As the chamber has a small capacity, the time required for evacuation can be shortened.

  • Publication number: 20050003635
    Abstract: A dicing method, integrated circuit element testing method, substrate holding apparatus, and adhesive film are disclosed. A first adhesive film 22 in which the adhesion is reduced by ultraviolet radiation is stretched inside a ring-like frame 21 larger than a wafer size, and a wafer W is adhered on the first adhesion film 22. A second adhesive film 4 in which the adhesion of the two surfaces is reduced by heating is adhered on a plate-like jig 3. After the first film is adhered on the second film, dicing is performed. Since the wafer is adhered to the jig, the relative positions of chips do not shift from each other. This makes it possible to load the wafer together with the jig into a testing apparatus and align electrode pads of the chips with a probe. This allows, e.g., collective testing of a plurality of chips.
