Patent ID: 7993820

Claim:
A pattern manufacturing equipment for manufacturing a pattern on a transparent substrate having a pattern of a number of identical gate electrodes formed regularly thereon, comprising: a lyophobic film applicator means for applying a lyophobic film on the transparent substrate; an exposure means placed on the back of the transparent substrate for forming the lyophobic film applied on the transparent substrate into a pattern in alignment with the pattern of the gate electrodes; a liquid dropping means for dropping a test liquid to form a first droplet of the test liquid on a surface of the lyophobic film formed by the exposure means and to drop a second droplet of the test liquid to a surface of the transparent substrate where the lyophobic film has been removed; a measuring means for detecting diameters of the first and second droplets dropped by the liquid dropping means; and a determining means for determining whether the lyophobic film has been properly formed by the exposure means based on the diameter of the first droplet and for determining whether the lyophobic film has been removed from the surface of the transparent substrate by determining the diameter of the second droplet.
