Abstract:
1. A substrate processing method for performing a heat process on a plurality of substrates each with a coating film formed thereon to bake and cure the coating film, while sequentially transferring the substrates, the method comprising: distinguishing the substrates from each other in accordance with a first state and a second state where an elapsed time length since formation of the coating film is shorter and not shorter, respectively, than a predetermined time length; holding each substrate having the first state at a preparatory temperature lower than a lower limit of temperature for baking and curing the coating film, to adjust distribution of a predetermined component in the coating film, and then subjecting the substrate having the first state to a heat process at a temperature not lower than the lower limit of temperature; and subjecting each substrate having the second state to a heat process at a temperature not lower than the lower limit of temperature, without holding the substrate having the second state at a temperature lower than the lower limit of temperature.
