Claim:
1. A method for processing a substrate, comprising: forming a photosensitive film on a front surface of a substrate; measuring a back surface of the substrate such that measured warping data of the substrate having the photosensitive film formed thereon are acquired; determining whether roughening process is to be applied on the back surface of the substrate based on the measured warping data prior to transferring the substrate to an exposure device; transferring the substrate having the photosensitive film to the exposure device after acquisition of the measured warping data; and transmitting the measured warping data to the exposure device, wherein the roughening process comprises roughening the back surface of the substrate based on the measured warping data to a degree that Coulomb's force between a mounting plate of the exposure device and the back surface of the substrate decreases and that the back surface of the substrate slides on the mounting plate of the exposure device when the back surface of the substrate is mounted on the mounting plate of the exposure device.
