Apparatus for stacking cassette and a method of fabricating a liquid crystal display device using the same

1. A method of fabricating a liquid crystal display (LCD) device, the method comprising:

holding a first substrate of the LCD device and a second substrate of the LCD device in a cassette of a cassette stacking apparatus;

removing the cassette from the cassette stacking apparatus;

removing the first substrate and the second substrate from the cassette;

performing an array process on the first substrate;

performing a color filter process on the second substrate;

attaching the first and second substrate together; and

cutting the attached substrates into a plurality of unit LCD panels,

wherein the cassette stacking apparatus includes first loading unit that loads or unloads a cassette, a plurality of stacking units disposed at a side of the loading unit where an upper portion of the stacking unit forms a shelf that receives the cassette where the cassette is removed from the shelf such that the array process and the color filter process may be performed on the first and second substrates and a plurality of process equipment for processing substrates disposed in the cassette, and

wherein the plurality of process equipment and the plurality of stacking units have a cluster configuration such that the plurality of process equipment are disposed along a side of the plurality of stacking units.

2. The method of claim 1 , wherein the loading unit further including a robot arm for conveying the cassette.

3. The method of claim 2 , wherein the loading unit further including a driving unit that drives the robot arm and operates the loading unit.

4. The method of claim 2 , wherein a height of the stacking unit allows operation of the robot arm.

5. The method of claim 1 , wherein the cassette stacking apparatus further includes a second loading unit wherein the first loading unit and the second loading unit are formed at the front and rear of the cassette stacker.

6. The method of claim 5 , wherein the second loading unit loads the cassette onto the cassette stacking apparatus when the first loading unit is non-functional.
