The adhesive composition according to the present invention includes a resin containing a polymer having an alkoxystyrene structure as a repeating unit, and an acid generator. In accordance with the present invention, it is possible to provide a novel adhesive composition which is excellent in heat resistance and which is easily stripped.
摘要:
A method for stripping a wafer from a supporting plate to which the wafer is adhered via an adhesive agent, wherein the supporting plate has a through hole penetrating the supporting plate in a thickness direction thereof, the method including dissolving the adhesive agent with a stripping solution by contacting the stripping solution with the adhesive agent via the through hole. The adhesive agent has a hydrocarbon resin as a viscous component, and the stripping solution is a hydrocarbon-based solvent having a viscosity of 1.3 mPa·s or less and a dissolving rate of 30 nm/sec or greater to dissolve the adhesive agent.

A sticking method for sticking a support plate onto a substrate in such a way that the support plate can be removed in quickly and easily is provided. The sticking method according to the present invention includes the step of sticking a support plate 3 onto a wafer 2 via a first adhesive layer 4 provided on the wafer 2, a separate film 5 provided on the first adhesive layer 4, and a second adhesive layer 6, provided on the separation film layer 5, which either is higher in rate of dissolution in a solution than the first adhesive layer 4 or dissolves in a solvent different from the solvent in which the first adhesive layer 4 dissolves.
摘要:
This invention provides a support plate which makes it possible to stably perform a step for separating from a support plate a wafer which has been processed while preventing delay in time taken for this step. The support plate of this invention is a support plate for supporting a substrate via an adhesive, including: a plate-shaped part having a surface which is in contact with the adhesive; and at least one spacer provided on the surface which is in contact with the adhesive.

Disclosed is an adhesive composition in which a solid component is dissolved in a solvent, the solid component being dissolved in the solvent to have a solid component content of not less than 20% by weight with respect to a total amount of the solid component and the solvent, the solid component containing resin obtained by polymerizing a monomer composition that contains a cycloolefin monomer, the solvent having no carbon-carbon double bond, and an alcohol content contained in the solvent being not more than 0.45% by weight with respect to an entire amount of the solvent.
摘要:
A laminate including a supporter which transmits infrared; a substrate supported by the supporter; an adhesive layer via which the supporter and the substrate are attached to each other; and a separation layer, positioned on a surface of the supporter to which surface the substrate is attached, and made of a compound having an infrared-absorbing structure.
摘要:
A method for supporting a support to which a wafer is attached, by supporting the support against gravitational force by supporting three or more support points of an inner circumference section of a support surface of the support. The support surface of the support is opposite to a side on which the wafer is attached to the support.
摘要:
An adhesive composition of the present invention is an adhesive composition including a polymer obtained by copolymerizing a monomer composition containing a (meth)acrylic acid ester and a monomer having a maleimide group, the (meth)acrylic acid ester has a structure represented by General Formula (1): wherein R1 is a hydrogen atom or a methyl group, and R2 is a C4 to C20 alkyl group, and the (meth)acrylic acid ester is contained in the monomer composition by 10 to 50 parts by mass where an amount of the monomer composition is 100 parts by mass. With the arrangement, it is possible to provide an adhesive agent and a film adhesive each of which can be suitably used in high temperature processing.
