The present invention relates to an adhesive film comprising an adhesive layer; a photothermal conversion layer containing a light absorber and a thermally decomposable resin; and an adhesive base film layer disposed between the adhesive layer and the photothermal conversion layer, wherein the adhesive base film layer contains a multifunctional epoxy resin, a binder resin, a curing agent, and a curing catalyst. The adhesive film according to the present invention may be able to simplify a processing process of a substrate, and prevent damage to the substrate and circuits or elements formed on the substrate.

Adhesive film

The present disclosure relates to an adhesive film, and adhesive film includes: a photothermal conversion layer including a light absorbing agent and a pyrolytic resin; an adhesive base film layer disposed on the photothermal conversion layer; a buffer layer disposed on the adhesive base film layer; and an adhesive layer disposed on the buffer layer, and the buffer layer includes a polysiloxane resin, and the adhesive layer includes a silicon-based adhesive, and the silicon-based adhesive includes a silicon-based tackifier and a polysiloxane resin. The adhesive film according to the present disclosure can simplify a process of processing a substrate, and can prevent a damage of the substrate and a circuit or an element formed on the substrate.

The present invention relates to an adhesive film including a photothermal conversion layer including a light absorber and a thermally decomposable resin; and an adhesive layer, in which the thermally decomposable resin has a &#x2014;COOH or &#x2014;OH functional group and includes two kinds of acrylic resins having different weight average molecular weights, and an adhesive substrate including the adhesive film and a substrate to be processed. In the adhesive film and the adhesive substrate according to the present invention, it is possible to simplify a processing process of the substrate and reduce costs and time, and prevent damage to a substrate and a circuit or an element formed on the substrate.
