Patent ID: 8021993

Claim:
A method of carrying out an exposure process for a liquid crystal display device comprising: conveying a substrate coated with photoresist to a thru-conveyor using a first robot arm; unloading the substrate from the thru-conveyor and conveying the substrate to a hot plate using a second robot arm; removing solvent from the substrate at the hot plate; after removing solvent, conveying the substrate to a cold plate using the second robot arm; lowering a temperature of the substrate at the cold plate; after lowering the temperature, conveying the substrate to a buffer using the second robot arm; temporarily storing the substrate in the buffer; after storing, conveying the substrate to a temperature control unit by a third robot arm; adjusting the temperature of the substrate in the temperature control unit; after adjusting the temperature, conveying the substrate to the exposure unit using the third robot arm; exposing the substrate to ultraviolet radiation in the exposure unit.
