Abstract
Abstract Disclosed is a device for clearing the hole blockage of a liquid resist substrate. The liquid resist substrate has a substrate formed with holes and coated on its upper surface with a liquid resist. The device has a blowing-off means which is intended to blow off the portions of the liquid resist in the holes from the same to an upper surface side of the substrate, and a sucking-in means which is intended to suck in the portions of the liquid resist in the holes of the substrate, whereby the portions of the liquid resist in the holes of the substrate can be removed.
