Provided is a new method by which it is easier to remove an element after processing, so as to improve productivity in manufacturing an electronic component or a semiconductor device. An object to be processed used in manufacturing an electronic component or a semiconductor device is attached to an uneven surface of a pressure sensitive adhesive layer. The object to be processed on the pressure sensitive adhesive layer is processed to obtain a processed product. The processed product is removed from the pressure sensitive adhesive layer.

A pressure sensitive adhesive sheet includes a pressure sensitive adhesive layer catching elements distant from a holding substrate. The pressure sensitive adhesive layer has unevenness on a surface and having a complex shear elastic modulus at 23 C. of 0.001 MPa or greater and 1.0 MPa or less.

An adhesive film liner comprising (a) a polymeric layer having a first and a second surface, the second surface being opposed to the first surface; (b) a first release layer located on top of the first surface of the polymeric layer, the first release layer comprising at least one polyurethane acrylate oligomer and/or at least one polyurethane methacrylate oligomer; and (c) a second release layer located on top of the second surface layer of the polymeric layer, the second release layer comprising at least one acrylate polymer.

The present disclosure discloses an encapsulation adhesive film 100, comprising an adhesive film body and a surface pattern provided on at least one surface of the adhesive film body, and the surface pattern comprising a first pattern extending basically along a first direction and a second pattern extending basically along a second direction, the first direction intersecting the second direction at a predetermined angle , the predetermined angle being greater than 0 and less than 180; the surface pattern comprising at least one of the first pattern and at least one of the second pattern.
