CONSTITUTION: A plurality of fine holes are formed on an upper side of a polishing pad in order to store slurries. A gas injection nozzle array(510) is used for injecting gas to an upper side of the polishing pad while the polishing pad is in the idling state after a polishing process. The gas injection nozzle array includes a plurality of injection nozzles(511). The gas injection nozzle is installed at an upper side of the polishing pad. The gas injected from the gas injection nozzle is formed with nitrogen gas.

Abstract: PURPOSE: A carbon nano-tube transistor having a buried gate structure and a fabricating method thereof are provided to apply effectively the gating electric field to a carbon nano-tube by forming a gate having a buried structure around the carbon nano-tube. CONSTITUTION: A carbon nano-tube transistor includes a carbon nano-tube(110), a source electrode(130) and a drain electrode(120) connected electrically to both ends of the carbon nano-tube, and a gate electrode(142) having an extension part. The extension part of the gate electrode is formed at a predetermined position apart from the carbon nano-tube. The carbon nano-tube and the extension part of the gate electrode are buried into an insulating layer. The insulating layer is formed with an anodic aluminum oxide.
