    摘要: A showerhead electrode and assembly useful for plasma etching includes cam locks which provide improved thermal contact between the showerhead electrode and a backing plate. The cam locks include cam shafts in the backing plate which engage enlarged heads of studs mounted on the showerhead electrode. The assembly can include an annular shroud surrounding the showerhead electrode and eight of the cam shafts in the backing plate can be operated such that each cam shaft simultaneously engages a stud on the annular shroud and a stud in an outer row of studs on the showerhead electrode. Another eight cam shafts can be operated such that each cam shaft engages a pair of studs on inner and middle rows of the studs mounted of the showerhead electrode.

    摘要: A plasma processing systems having at least one plasma processing chamber, comprising a movable grounding component, an RF contact component configured to receive RF energy from an RF source when the RF source provides the RF energy to the RF contact component, and a ground contact component coupled to ground. The plasma processing system further includes an actuator operatively coupled to the movable grounding component for disposing the movable grounding component in a first position and a second position. The first position represents a position whereby the movable grounding component is not in contact with at least one of the RF contact component and the ground contact component. The second position represents a position whereby the movable grounding component is in contact with both the RF contact component and the ground contact component.

    摘要: An electrode assembly for a plasma reaction chamber used in semiconductor substrate processing. The assembly includes an upper showerhead electrode which includes an inner electrode mechanically attached to a backing plate by a clamp ring and an outer electrode attached to the backing plate by a series of spaced apart cam locks. A guard ring surrounds the backing plate and is movable to positions at which openings in the guard ring align with openings in the backing plate so that the cam locks can be rotated with a tool to release cam pins extending upward from the upper face of the outer electrode. To compensate for differential thermal expansion, the clamp ring can include expansion joins at spaced locations which allow the clamp ring to absorb thermal stresses.

    摘要: A cam lock clamp comprises a stud having a substantially cylindrical body with a first end including a head area and a second end arranged to support one or more disc springs concentrically about the stud. A socket is arranged to mechanically couple concentrically around the stud with the head area of the stud being exposed above an uppermost portion of the socket. The socket is configured to be firmly attached to a consumable material. A camshaft has a substantially cylindrical body and is configured to mount within a bore of a backing plate. The camshaft further comprises an eccentric cutout area located in a central portion of the camshaft body. The camshaft is configured to engage and lock the head area of the stud when the consumable material and the backing plate are proximate to one another.
