Patent number: 8167687Abstract: A wafer can be thinned without occurrences of dimples. A support plate 1 has a number of through holes 10. A circuit forming surface of a wafer 2 is adhered to one surface of the support plate by an adhesive member 4, and a dimple prevention member 3 having a thickness of 100 ?m or more and having an adhesive layer 30 on one face is adhered to the other surface, thus the openings at both ends of the through holes 10 are blocked. The support plate is vacuum adsorbed to a support table through the dimple prevention member, and a non circuit-forming face of the wafer is ground/polished to thin the wafer. The dimple prevention member is stripped off, and a solvent is penetrated into the adhesive member through the through holes to detach the wafer from the support plate.Type: GrantFiled: May 24, 2007Date of Patent: May 1, 2012Assignee: Tokyo Ohka Kogyo Co., Ltd.Inventors: Akihiko Nakamura, Atsushi Miyanari, Yoshihiro Inao, Yasumasa Iwata

Patent number: 8148457Abstract: Disclosed is an adhesive composition whose component is a polymer obtained by copolymerizing a monomer composition containing styrene, a (meth)acrylic acid ester having a cyclic structure, and an alkyl(meth)acrylate having a chain structure. The monomer composition further contains a carboxylic acid having an ethylene double bond, a bifunctional monomer, and a styrene macromonomer. The polymer has a styrene block segment. This can improve heat resistance, adhesive strength in a high temperature environment, alkaline resistance, and easiness in stripping of an adhesive composition that has been subjected to a high temperature process. As a result, there can be obtained an adhesive composition which has high heat resistance, adhesive strength in a high temperature environment, and alkali resistance, and which can be easily stripped off after the adhesive composition is processed at a high temperature.Type: GrantFiled: September 26, 2007Date of Patent: April 3, 2012Assignee: Tokyo Ohta Kogyo Co., Ltd.Inventors: Takahiro Asai, Koichi Misumi, Atsushi Miyanari, Yoshihiro Inao, Akihiko Nakamura
