  • Patent number: 9327418
    Abstract: An adhesive film includes a film-like adhesive layer and a pair of separators sandwiching the adhesive layer. The outer edges of both separators extend outward beyond the outer edge of the adhesive layer, and a blade is used to form a notch on the adhesive layer side of the heavy release separator, along the outer edge of the adhesive layer. The thickness of the heavy release separator is between 50 ?m and 200 ?m, the average notch depth is between 5 ?m and 45 ?m and the standard deviation for the notch depth is no greater than 15 ?m. Specifying the notch depth allows complete cutting of the adhesive layer with the blade, while also limiting release problems between the heavy release separator and the adhesive layer.

  • Publication number: 20150239220
    Abstract: The adhesive film includes a film-like adhesive layer, a light release separator and a heavy release separator that are laminated on either side of the adhesive layer, and a carrier film further laminated on the heavy release separator. The outer edges of the light release separator and the carrier film forming the outer layer extend outward beyond the outer edge of the adhesive layer and the heavy release separator forming the inner layer. The outer edge sections of the adhesive layer are thereby protected. The outer edge section of the carrier film is gripped and released first, after which the outer edge section of the light release separator is gripped and released, and finally the heavy release separator is released, thereby allowing each separator and the carrier film to be reliably and easily released in the prescribed order.

  • Patent number: 8617930
    Abstract: The invention provides an adhesive sheet which can be stuck to a wafer at low temperatures of 100° C. or below, which is soft to the extent that it can be handled at room temperature, and which can be cut simultaneously with a wafer under usual cutting conditions; a dicing tape integrated type adhesive sheet formed by lamination of the adhesive sheet and a dicing tape; and a method of producing a semiconductor device using them. In order to achieve this object, the invention is characterized by specifying the breaking strength, breaking elongation, and elastic modulus of the adhesive sheet in particular numerical ranges.
