Patent ID: 8221579

Claim:
A method of reusing a consumable part for use in a plasma processing apparatus, the method comprising: forming a silicon carbide (SiC) lump by depositing SiC by chemical vapor deposition (CVD); manufacturing a consumable part for the plasma processing apparatus by machining the SiC lump, the consumable part having a predetermined shape; performing a first plasma process on a substrate by using the manufactured consumable part; cleaning a surface of the consumable part that has been eroded by the first plasma process performed for a specific period of time; depositing SiC on the cleaned surface of the eroded consumable part by CVD; remanufacturing a consumable part having the predetermined shape by machining the eroded consumable part on which the SiC is deposited; and performing a second plasma process on a substrate by using the remanufactured consumable part.
