Provided are a lift pin capable of preventing aluminum from depositing on the lift pin when depositing a metallic layer on a wafer through chemical vapor deposition. a system using the lift pin, and a method of manufacturing the same. The lift pin is made of stainless steel and is oxidized at a predetermined temperature for a predetermined time, such that the lift pin is not deposited with aluminum during a CVD process. Since the CVD vacuum processing chamber utilizes the heater and the lift pin which are made of oxidized SUS material, aluminum does not deposit on the heater and the lift. Therefore, when the lift pin is lowered, the lift pin is not lowered by its own weight, thereby preventing a wafer from being broken. Also, the lift pin is prevented from being ruptured by a robot moving in and out of an opening of the CVD vacuum processing chamber. |
