Substrate treating apparatus and method of treating substrate

A method of treating a substrate using a substrate treating apparatus comprising a plurality of conveying rollers which transfer the substrate in a horizontal direction, the method comprising:

• forming a developer layer by providing a developer onto the substrate;
• moving a first conveying roller which is closest to a front end of the substrate in a transferring direction and does not contact the substrate away from the substrate;
• transferring the substrate on which the developer layer is formed in the horizontal direction by rotating the plurality of conveying rollers;
• moving the first conveying roller vertically upward to make the first conveying roller contact the lower surface of the substrate;
• and
• transferring the substrate in the horizontal direction by rotating the first conveying roller and a plurality of conveying rollers which contact with the substrate.

A method of treating a substrate using a substrate treating apparatus comprising a plurality of conveying rollers which transfer the substrate in a horizontal direction, the method comprising:

• forming a developer layer by providing a developer onto the substrate on the conveying rollers positioned at a first height and in contact with a lower surface of the substrate;
• and
• transferring the substrate on which the developer layer is formed in the horizontal direction by rotating the conveying rollers positioned at the first height, and
• wherein as the substrate is transferred, the conveying rollers located at a second height which is lower than the first height and adjacent to a front end of the substrate is moved vertically upward to contact with a lower surface of the substrate, and
• as the substrate is transferred, the conveying rollers located at the first height which is adjacent to a rear end of the substrate is moved away from the substrate and be located at the second height.
