Abstract:
1. A fabricating apparatus comprising: a radio frequency generator; a vacuum chamber; a first electrode and a second electrode disposed inside the vacuum chamber to receive power; a radio frequency match box installed between the radio frequency generator and the first electrode; a first conductor to transmit power from the radio frequency generator to the radio frequency match box; a second conductor to transmit the power from the radio frequency generator to the first electrode; a cooling system to keep a first refrigerant below a designated temperature; a cooling part installed at the second conductor; and including a first tube to supply the first refrigerant from the cooling system to the cooling part; and a second tube to discharge the first refrigerant from the cooling part to the cooling system; a gas supplier through which the gas flows into the vacuum chamber; wherein the cooling part includes an insulating tube covering the second conductor, and a plurality of refrigerant tubes installed inside the insulating tube to contain a second refrigerant, and a third tube surrounding the insulating tube; wherein the first refrigerant circulates through the third tube; and wherein the second refrigerant exchanges a heat with the second conductor to circulating the plurality of refrigerant tubes and the first refrigerant exchanges a heat with the insulating tube to circulating the third tube.
