Patent ID: 8377205

Claim:
An apparatus for producing silicon nanocrystals comprising: a gas supply part, into which a tube is inserted to allow a primary gas for forming silicon nanocrystals and a secondary gas for surface reaction of the silicon nanocrystals to be separately supplied through an inner side and an outer side of the tube, respectively; a reactor located below the gas supply part and having an ICP coil wound around an outer wall thereof, wherein the primary gas for forming silicon nanocrystals is supplied directly to the reactor through the inner side of the tube in order to create a narrow plasma reacting region and the secondary gas for surface reaction of the silicon nanocrystals is separately supplied to the reactor through the outer side of the tube; a dispersing part located below the reactor to rapidly cool and disperse the silicon nanocrystals formed in the reactor; and a collecting part located below the dispersing part to collect the silicon nanocrystals.
