    摘要: A method for attaching a substrate such as a semiconductor wafer in which cracking or chipping can be prevented when the substrate is thinned involves applying adhesive liquid onto a circuit (element)-formed surface of a semiconductor wafer. The adhesive liquid undergoes preliminary drying, so that its flowability is reduced and it can keep its shape as an adhesive layer. For the preliminary drying, heating is conducted for 5 minutes at a temperature of 80° C. by using an oven. The thickness of the adhesive layer is determined based on the irregularities of the circuit which has been formed on the surface of the semiconductor wafer. Next, a supporting plate is attached to the semiconductor wafer on which the adhesive layer of a desired thickness has been formed.

    摘要: 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.

    摘要: An adhesive composition of the present invention contains, as a main composition, a polymer obtained by copolymerizing a monomer composition containing a monomer having a maleimide group, and further contains a thermal polymerization inhibitor. As a result, it is possible to provide an adhesive composition that allows forming an adhesive layer that is excellently dissolved after the adhesive layer has been subjected to a high-temperature process.
