Patent ID: 8158494

Claim:
A method for processing a substrate so as to partially remove the substrate by plasma etching, the method comprising: forming a liquid-repellent pattern by printing a liquid-repellent liquid on an area of a surface to be processed of the substrate, the area being to be removed by the etching; forming a resin film thicker than the liquid-repellent pattern by supplying a liquid resin to the surface to be processed on which the liquid-repellent pattern has been formed, the resin film being formed in an area not having the liquid-repellent pattern; forming a mask by curing the resin film, the mask being formed on the surface to be processed and covering the area other than the area to be removed by the etching; removing the liquid-repellent pattern from the surface to be processed after the mask is formed; plasma etching the substrate from a side of the surface to be processed after the liquid-repellent pattern is removed; and removing the mask from the surface to be processed after the etching.
