  • Publication number: 20110139611
    Abstract: In an apparatus for fabricating a thin film transistor, amorphous silicon is deposited on a substrate in a first multi-chamber and is crystallized into polycrystalline silicon without using a separate process chamber or multi-chamber, and the substrate deposited with the amorphous silicon is loaded into a second multi-chamber for forming electrodes, thereby making it possible to minimize a characteristic deviation and improve fabrication process efficiency. The apparatus includes a first multi-chamber in which amorphous silicon is deposited on a substrate, a second multi-chamber in which electrodes are formed on the substrate, and a loading/unloading chamber interposed between the first multi-chamber and the second multi-chamber. The loading/unloading chamber includes a substrate holder on a lower side thereof and a power voltage supplier on an upper side thereof.
