Patent number: 8691666Abstract: A method for producing a chip (13) in which a die bonding adhesive layer (24) and a wafer (1) are laminated on a close-contact layer (31) of a fixing jig (3), the chip is formed by completely cutting the wafer and the die bonding adhesive layer and then the chip is picked up together with the die bonding adhesive layer from the fixing jig by deforming the close-contact layer of the fixing jig. In the method the fixing jig is provided with the close-contact layer and a jig base (30) that is provided with a plurality of protrusions (36) on one side and a sidewall (35) at the outer circumference section of the one side. The close-contact layer is laminated on the surface of the jig base provided with the protrusions and is bonded on the upper surface of the sidewall. On the surface of the jig base provided with the protrusions, a partitioned space is formed by the close-contact layer, the protrusions, and the sidewall.Type: GrantFiled: April 15, 2008Date of Patent: April 8, 2014Assignee: Lintec CorporationInventors: Takeshi Segawa, Naofumi Izumi

Patent number: 8529314Abstract: When both surfaces of a wafer are sequentially subjected to processing, the wafer is made to be surely supported so that a predetermined processing and transporting can be performed. On one surface of the wafer a first fixing jig (3a) is fixed in close contact. After having performed a predetermined processing to the opposite surface of the wafer, a second fixing jig (3b) is fixed in close contact with the opposite surface of the wafer. The first fixing jig (3a) is removed and the wafer is handed over to the second fixing jig (3b). Each of the fixing jigs is made up of a jig main body (31), and a close contact layer (32) which is disposed on one surface thereof. The jig main body has a plurality of supporting projections (33) to support the close contact layer, and a side wall (34). The close contact layer is adhered to an end surface of the side wall to thereby define a partitioned space (35) enclosed by the side wall, between the close contact layer and the jig main body.Type: GrantFiled: July 31, 2008Date of Patent: September 10, 2013Assignees: Lintec Corporation, Shin-Etsu Polymer Co., Ltd.Inventors: Takeshi Segawa, Kiyofumi Tanaka

Patent number: 8465011Abstract: A fixing jig is made up of a plate-like jig main body (2) and a close contact layer (3) which detachably holds a work (W) in close contact therewith. The jig main body has: on one surface thereof a plurality of supporting projections (4) to support the close contact layer; and also has, along an outer peripheral portion of said one surface, a side wall (5) which is of substantially the same height as the supporting projections. The close contact layer is adhered to an end surface of the side wall to thereby define a partitioned space (6) between the close contact layer and the jig main body. By sucking the air within the partitioned space via a ventilation hole (7) formed in the jig main body, the close contact layer is deformed. The work is thus surely supported and fixed also in performing a processing in which a force is applied to the work.Type: GrantFiled: July 31, 2008Date of Patent: June 18, 2013Assignees: Lintec Corporation, Shin-Etsu PolymerInventors: Takeshi Segawa, Kiyofumi Tanaka
