Patent ID: 7985699

Claim:
A substrate processing method for a substrate processing system having at least an etching apparatus that carries out plasma etching processing on a substrate, the etching apparatus having therein an electrostatic chuck that electrostatically attracts the substrate and is adapted to contact a rear surface of the substrate, the method comprising: a first coating step of coating a rear surface of the substrate with curable resins; a curable resin curing step of curing the coated curable resins so as to form a resin protective film; an inverting step of inverting the substrate while holding a periphery of the substrate; a second coating step of coating a front surface of the substrate with resistant resins; a resistant resin curing step of curing the coated resistant resins; a resistant resin light exposure step of subjecting the cured resistant resins to light exposure processing; an etching step of carrying out the plasma etching processing on the front surface of the substrate; and a washing step of removing the cured curable resins and the coated resistant resins, wherein in said resistant resin light exposure step, the rear surface of the substrate is supported by pin-like projections such that the resin protective film is present between the rear surface of the substrate and the projections.
