Abstract:
In a method in which a workpiece, while being temporarily fixed on a support via a temporary fixing material, is processed and/or transported and thereafter the support and the workpiece are separated from each other by an irradiation separation method, a technique is shown which prevents the photo-degradation of the workpiece. A workpiece treating method includes a step of forming a stack including a support, a temporary fixing material and a workpiece wherein the temporary fixing material includes a layer (I) that contains a polymer (A) including a structural unit (A1); a step of processing the workpiece and/or transporting the stack; a step of applying light to the layer (I) through the support; and a step of separating the support and the workpiece from each other.

Claim (Index 1):
A workpiece treating method comprising:\n a step (1) of forming a stack including a support, a temporary fixing material and a workpiece wherein the temporary fixing material comprises a layer (I) that contains a polymer (A) including a structural unit represented by the formula (A1) below, and the workpiece is held on the temporary fixing material; a step (2) of processing the workpiece and/or transporting the stack; a step (3) of applying light to the layer (I) through the support; and a step (4) of separating the support and the workpiece from each other, wherein in the formula (A1), Ar is a condensed polycyclic aromatic ring; \u2014OR 1  is a group bonded to the condensed polycyclic aromatic ring wherein R 1  is a hydrogen atom or a hydrocarbon group with 1 to 20 carbon atoms and when a plurality of \u2014OR 1  are present, the \u2014OR 1  groups may be the same as or different from one another; R 2  is a group bonded to the condensed polycyclic aromatic ring and indicates a halogen atom or a hydrocarbon group with 1 to 20 carbon atoms wherein when a plurality of R 2  are present, the R 2  groups may be the same as or different from one another; R 3  groups are each a hydrogen atom or an organic group and the R 3  groups may be the same as or different from one another; and a is an integer of 1 or greater and b is an integer of 0 or greater.
