Abstract
A temporary adhesive material for substrate processing adhesion to support the substrate opposite to a surface, the material including: a first temporary adhesive layer; and a second temporary adhesive layer distinct from the first layer, where at least one of the first layer and the second layer has a minimum viscosity of 1 Pa·s or higher and 10,000 Pa·s or lower within 130° C. to 250° C., where: the temporary adhesive material contains 10 parts by mass or more and 100 parts by mass or less of a siloxane bond-containing polymer having a weight-average of 3,000 or more and 700,000 or less as measured by GPC based on a total mass of 100 parts. A temporary material for substrate processing that facilitates the adhesion and separation, allows a quick layer formation, has dimensional resistance to thermal processes, and can raise the productivity of substrates; and manufacturing a laminate using the same.
