Claim 0:
1. A wafer processing temporary adhesive for temporarily bonding a wafer to a support, comprising a photocurable silicone resin composition containing a non-functional organopolysiloxane,
wherein the photocurable silicone resin composition comprises:
(A) 100 parts by weight of an organopolysiloxane having at least two alkenyl groups per molecule,
(B) an organohydrogenpolysiloxane having at least two silicon-bonded hydrogen atoms (i.e., SiH groups) per molecule, in such an amount that a molar ratio of the total of SiH groups in component (B) to the total of alkenyl groups in component (A) is from 0.3 to 10,
(C) 0.1 to 200 parts by weight of the non-functional organopolysiloxane, and
(D) a photo-activatable hydrosilylation reaction catalyst in such an amount as to provide 0.1 to 5,000 ppm of metal atom based on the total weight of components (A), (B), and (C).
