Patent abstract
An adhesive sheet for processing semiconductor substrates comprises a UV rays- and/or radiation-transmittable base film and an adhesive layer that undergoes a polymerization curing reaction by means of UV rays and/or radiation, wherein the adhesive layer is formed using a multifunctional acrylate oligomer and/or monomer having a double bond, and is blended so as to result in 1 double bond per total average molecular weight of 225 to 8000 as determined on the basis of the weight average molecular weight of the multifunctional acrylate oligomer and/or monomer.
