Abstract:
1. A processing method for substrates, comprising: a step in which substrates before curing are mounted on a mounting table, said substrates having a plurality of individual substrates and an uncured photo-curable adhesive layer interposed between these individual substrates; a step in which substrates after curing are obtained wherein, while said substrates before curing are mounted on said mounting table, said individual substrates are bonded together by photo-curing said adhesive layer by irradiating said substrates before curing with photo-curing light; and a step in which a deflection X of said substrates after curing is controlled by controlling at least one of said substrates before curing and said mounting table; the step in which said deflection X is controlled comprises: a step in which a temperature difference ΔT between a temperature Th of said mounting table and a temperature Td of said substrates before curing is found; a step in which a deflection difference ΔX between the deflection X of said substrates after curing and a target deflection setting value Xt is found; a step in which a temperature Tc is found by Tc=ΔT−M×ΔX by using a constant of proportionality M determined by a correlation between said temperature difference ΔT and said deflection X; and a step in which at least one of said substrates before curing and said mounting table are temperature controlled according to said temperature Tc such that Tc=Th−Td.
