摘要:
A stripping apparatus has a simplified structure for stripping a supporting plate from a layered structure, occupies less space, and strips a supporting plate in a shorter period of time. The stripping apparatus comprises a transfer robot, a cassette, a stripping device and a cleaning device which surround the transfer robot. The stripping device comprises a chucking plate for attracting and retaining a layered structure, and a stripping plate for stripping the supporting plate from the layered structure. The chucking plate is constructed so as to be rotated by 180° within a vertical plane, elevated and lowered in a vertical direction in a state of retaining the layered structure.

In order to provide a liquid solvent abutment unit for accelerating the reaction of a liquid solvent against an adhesive member existing between a perforated support plate and a wafer, a liquid solvent abutment unit comprises: a supply part for supplying a support plate surface with a liquid solvent; a retention part for retaining the supplied liquid solvent in the hole-formed region on the support plate surface; a recovery part for recovering the liquid solvent retained in the hole-formed region; and a vibration unit for vibrating the liquid solvent.
摘要:
A method for attaching a supporting plate which makes it possible to prevent the groove pattern of the supporting plate from being transferred to the substrate, and to prevent non-uniformity from occurring when the surface of the substrate is ground. One surface of the supporting plate is attached to the substrate with an adhesive, and the opposite surface of the supporting plate to which a transfer preventing sheet is attached is mounted and fixed by attraction onto the top surface of an attracting head, and the top surface (no circuit is formed) of the semiconductor wafer is ground by a grinder in this state.

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.

An attaching device which makes it possible to accurately perform alignment when the diameters of a substrate and a supporting plate are substantially the same includes a mounting plate for mounting a semiconductor wafer thereon, a pressing plate for pressing a supporting plate onto the semiconductor wafer, and a pair of alignment members. The pair of alignment members are arranged to freely move back and forth in a horizontal direction, and blades for supporting a lower surface of the periphery of the supporting plate and pushing members for performing positioning in a state where the supporting plate is superposed on the semiconductor wafer are provided at tip ends of the alignment members.

摘要:
An adhesive composition according to the present invention is an adhesive composition whose main component is a polymer obtained by copolymerization of a monomer composition, which monomer composition contains styrene, (meth)acrylic ester having a cyclic structure, and alkyl (meth)acrylate having a chain structure. The polymer thus having a styrene block segment allows improvement of thermal resistance, adhesive strength in a high temperature environment, alkaline resistance, and easiness in stripping following a high temperature process of the adhesive composition. As such, an adhesive composition is provided, which has high thermal resistance, adhesive strength in the high temperature environment, and alkaline resistance, and further which can easily carry out stripping of the adhesive composition after a high temperature process has been carried out to the adhesive composition.
