Patent number: 8171977Abstract: A sheet peeling apparatus 10 comprises: a supporting means 11 for supporting a semiconductor wafer W stuck with an adhesive sheet S; a feeding means 12 for feeding out a peeling tape T; a sticking means 14 for sticking the peeling tape T to the adhesive sheet S; a holding means 15 for holding a tip side in a feeding direction of the peeling tape T; and a peeling means 16 for imparting a peeling force to the adhesive sheet S. The peeling means 16 includes a peeling roller 44, and the peeling roller 44 abuts against an adhesive agent layer side of the peeling tape T stuck on the adhesive sheet S, and peeling off the adhesive sheet S in a state in which a turned-back portion c is formed by turning back a peeled end side of the adhesive sheet S.Type: GrantFiled: August 27, 2009Date of Patent: May 8, 2012Assignee: Lintec CorporationInventor: Kenji Kobayashi

Patent number: 8038824Abstract: A sheet peeling apparatus 10 includes: a supporting means 11 for supporting a semiconductor wafer W stuck with an adhesive sheet S; a tape sticking means 14 for sticking a peeling tape T to the adhesive sheet S; a pulling means 13 for pulling the peeling tape T; a peeling assisting means 15 including an endless member 45 which is positioned on the adhesive sheet S, and wound on a guide member 41; and a sandwiching means 16 for sandwiching the adhesive sheet S between the endless member 45 and the sandwiching means 16. In the sheet peeling apparatus 10, the adhesive sheet S is peeled off due to the relative movement of the pulling means 13 and the supporting means 11 in a state that the adhesive sheet S is sandwiched between the peeling assisting means 15 and the sandwiching means 16.Type: GrantFiled: July 22, 2009Date of Patent: October 18, 2011Assignee: Lintec CorporationInventors: Kenji Kobayashi, Takahisa Yoshioka, Takeshi Takano

Patent number: 8038839Abstract: Provided is a laminated body comprising a substrate to be ground and a support, where the substrate is ground to a very small thickness and can then be separated from the support without damaging the substrate. One embodiment of the present invention is a laminated body comprising a substrate to be ground, a joining layer in contact with the substrate to be ground, a photothermal conversion layer comprising a light absorbing agent and a heat decomposable resin, and a light transmitting support. After grinding the substrate surface which is opposite that in contact with the joining layer, the laminated body is irradiated through the light transmitting layer and the photothermal conversion layer decomposes to separate the substrate and the light transmitting support.Type: GrantFiled: October 22, 2009Date of Patent: October 18, 2011Assignee: 3M Innovative Properties CompanyInventors: Kazuki Noda, Masaru Iwasawa

Patent number: 8012307Abstract: A separating device for separating an electronic main body from a substrate bonded thereto comprises a platform, a conveying section, a dissolving section, a cleaning section, and a first partition plate. The conveying section is disposed on the platform for moving the electronic main body and the substrate forward. The dissolving section is disposed on the platform for spraying a solvent onto the bonded electronic main body and substrate. The cleaning section is also disposed on the platform for cleaning the electronic main body. The first partition plate is located between the dissolving section and the cleaning section and has at least one first slot, which allows only the electronic main body but not the substrate to pass therethrough, so that the electronic main body is separated from the substrate at the first partition plate. A method for separating the electronic main body and the substrate is also provided.Type: GrantFiled: August 12, 2009Date of Patent: September 6, 2011Assignee: Asia IC Mic-Process, Inc.Inventors: Yuan-Hsin Li, Chiu-Feng Yang

Publication number: 20110139375Abstract: An adhesive tape joined to a wafer is irradiated with ultraviolet rays via diodes. Simultaneously, a heater heats the adhesive tape to a preset temperature. Consequently, an ultraviolet reaction with the diodes and an infrared reaction with the heater may ensure promotion of a polymerization reaction, which results in cure of an adhesive that is not curable with only ultraviolet rays. As a result, an adhesive force of the adhesion tape may sufficiently be reduced. After ultraviolet irradiation via the diodes and heating with the heater, a separation mechanism separates the adhesive tape from the wafer. Therefore, accurate separation may be realized of the adhesive tape joined to the wafer.Type: ApplicationFiled: December 13, 2010Publication date: June 16, 2011Inventors: Masayuki Yamamoto, Masaru Irie
