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 device (Flat Panel Display device, referred to as: FPD) (such as liquid crystal display device (Liquid Crystal Display device, referred to as: LCD), plasma display panel device (PlasmaDisplay Panel device, referred to as: PDP), 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...
