Patent ID: 7520936

Claim:
A hardening processing apparatus for heating a substrate coated with a coating solution to harden a coating film on the substrate, comprising: a first processing chamber for mounting the substrate coated with the coating solution on a heating plate and heating the substrate to a predetermined temperature on a one-by-one basis; a first irradiation unit provided in said first processing chamber, for irradiating the substrate mounted on said heating plate with ultraviolet light; a second processing chamber connected in a communicating manner to said first processing chamber, for mounting the substrate coated with the coating solution on a temperature adjusting plate and adjusting the substrate to a temperature lower than a processing temperature of hardening processing on a one-by-one basis; and a second irradiation unit provided in said second processing chamber for irradiating the substrate mounted on said temperature adjusting plate with ultraviolet light having a wavelength different from that of said first irradiation unit.
