Abstract

The present invention presents a substrate transfer apparatus comprising: a tray on which a substrate is loaded; a magnetic transfer unit provided at a lower side of the tray, magnetically levitating the tray, and transferring the tray by magnetic force; a guide unit for guiding the transfer of the tray by not making contact with the tray; and an interval maintenance means provided at at least one region between the magnetic transfer unit and the guide unit.

Description

technical field [0001] The present invention relates to a substrate transfer device, and more particularly to a substrate transfer device that transfers a tray mounted with a substrate via a contactless method. Background technique [0002] Generally speaking, Flat Panel Display devices (FPD for short) (such as Liquid Crystal Display devices (LCD for short), Plasma Display Panel devices (PDP for short), field emission Field Emission Display device (FED for short) and Electroluminescence Display device (ELD for short) are manufactured by performing multiple processes on a substrate. That is, on the substrate, a deposition process, a photolithography process, and an etching process are repeated multiple times, and cleaning, attaching, and cutting processes are additionally performed to manufacture a flat panel display device. [0003] Such manufacturing processes of flat panel display devices are performed inside a plurality of chambers in which optimal environments are prepa...
