    Abstract: ESC의외주부에퇴적된 CF 베이스며 Si 및 Al를함유하는숄더퇴적물을효율적으로제거하는챔버내 클리닝방법을제공한다. O가스와 F 함유가스와의혼합가스를 ESC(24)의외주부(24a)를향하여압력 400 ~ 800 mTorr로공급하고, 상기혼합가스로부터생성된플라즈마를 ESC(24)의외주부(24a)에선택적으로조사하고또한, ESC(24)의외주부(24a) 이외의상부표면에마스킹가스로서 O단가스를공급하고, ESC(24)의외주부(24a) 이외의상부표면의 F 래디컬에의한피폭을방지하면서상기외주부(24a)에부착된숄더퇴적물(50)을분해, 제거한다.

    Abstract translation: 提供一种能够有效地除去沉积在ESC外周上的含有Si和Al的CF系肩层沉积物的室清洗方法。 在约400mTorr至约800mTorr的压力下,向ESC24的外周边24a供应O 2气体和F气体的混合气体; 从混合气体产生的等离子体照射到ESC24的外周24a上; 作为掩模气体的O 2单体气体除外周边24a供给到ESC24的上表面; 并且附着在外周24a上的肩部沉积物50被分解除去,同时防止除了外周边24a之外的ESC 24的顶面暴露于F基。

    Abstract: PURPOSE: A chamber cleaning method is provided to efficiently remove deposits attached to the outer surface of an electrostatic chuck by selectively radiating plasma generated from mixed gas to the outer surface of the electrostatic chuck. CONSTITUTION: Mixed gas of O2 gas and F containing gas is supplied to an outer surface(24a) of an ESC(24) with 400 to 800 mTorr. Plasma generated from the mixed gas is selectively radiated to the outer surface of the ESC. O2 gas is supplied to the upper surface except for the outer surface of the ESC as masking gas. A shoulder deposit(50) is decomposed and removed from the outer surface while preventing the upper surface except for the outer surface of the ESC from being exposed to F radical.

    Abstract: PURPOSE: A plasma processing apparatus is provided to effectively perform a uniform process by modifying imbalance due to an installation state of a ground member for a DC voltage. CONSTITUTION: A processing chamber(11) includes a processing space(PS). A lower electrode(12) is installed in the processing chamber. An upper electrode(36) faces the lower electrode in the chamber. An electrostatic chuck(27) including an electrode plate(26) is installed in dielectric which is in an upper side of the lower electrode. A DC power(28) for the electrostatic chuck is electrically connected with the electrode plate of the electrostatic chuck.
