Abstract:
1. A substrate coater for spreading a slurry supplied on one side of a substrate formed with a plurality of flow channels in parallel with each other into the flow channels by an air pressure thereby coating the inner wall of the flow channels, the substrate coater comprising: a slurry supplier that supplies a slurry by a necessary amount to a slurry storing part formed above the upper surface of a substrate disposed such that ends of the channels are opened to the upper surface and the bottom surface, respectively, an air chamber supporting the substrate, and a liquid surface leveler that makes the slurry liquid surface uniform before spreading the slurry in the flow channels, in which the liquid surface leveler comprises a rotary table having a hole that penetrates through both the upper and lower surfaces of the rotary table so as to allow passage of the substrate through the rotary table, the hole configured to allow the substrate to be fitted within the hole so as not to cover the flow channels and such that the flow channels of the substrate are opened at upper end of the substrate to an outside of the air chamber and opened at a lower end of the substrate into an inside of the air chamber, the rotary table rotating the substrate and slurry storing part around a vertical axis passing therethrough to level the liquid surface of the slurry by utilizing a centrifugal force by rotation in a state of storing the slurry in the slurry storing part.
