Patent ID: 7044183

Claim:
A processing apparatus for substrates, comprising: a mounting table for mounting substrates before curing, the substrates consisting of a pair of individual substrates having a photo-curable adhesive layer interposed therebetween; an irradiating device that irradiates the substrates before curing with a curing light while the substrates before curing are mounted on the mounting table; and a control device for controlling a deflection of the substrates X after curing by carrying out temperature control of at least one of the substrates before curing and the mounting table while the individual substrates are bonded together by photo-curing the adhesive; the control device comprises: a device that calculates a temperature difference ΔT between a temperature Th of the mounting table and a temperature Td of the substrates before curing; a device that finds a deflection difference ΔX between the deflection X of the substrates after curing and a target deflection setting value Xt; a device that finds a temperature Tc by calculating Tc=ΔT−M×ΔX by using a constant of proportionality M determined by a correlation between the temperature difference ΔT and the deflection X; and a device that carries out temperature control of at least one of the substrates before curing and the mounting table according to the temperature Tc such that Tc=Th−Td.
