Patent ID: 8293652

Claim:
A substrate processing method for partially eliminating a substrate by etching using plasma processing, the method comprising: a lyophobic pattern formation step of printing, on a processing target surface of the substrate, a lyophobic liquid to an area to be etched away and a contour set along an outer edge of the substrate to a predetermined width, thereby forming a lyophobic pattern; a resin film formation step of supplying a liquid resin on the processing target surface of the substrate on which the lyophobic pattern is formed, thereby forming a resin film that is thicker than the lyophobic pattern in an area where the lyophobic pattern is not formed; a mask formation step of curing the resin film, to thus form on the processing target surface a mask for covering an area except for the area to be etched away; a lyophobic pattern removal step of removing the lyophobic pattern from the processing target surface after performance of processing pertaining to the mask formation step; an etching step of etching the substrate from the processing target surface thereof by plasma processing after processing pertaining to the lyophobic pattern removal step; and a mask removal step of removing the mask from the processing target surface after completion of processing pertaining to the etching step.
