Abstract

See full text

Provided is a method of peeling an electronic member from a laminate composed of the electronic member adhered to a supporting substrate via an adhesive film having a self-peeling adhesive layer in a defined location and having an exposed region A. The method includes the steps of: reducing adhesive strength between the supporting substrate and the self-peeling adhesive layer in the region A by applying energy on the region A; removing the supporting substrate from the laminate by further applying energy on the region and thus further reducing the adhesive strength reduced in the prior step between the supporting substrate and the self-peeling adhesive layer from a starting point of the interface between the supporting substrate and the self-peeling adhesive layer; and peeling the electronic member from the laminate by removing the adhesive film from the electronic member.
