Patent ID: 7393432

Claim:
A plasma processing system comprising: an electrode; an RF conduction path structure, said RF conduction path structure being configured to provide an RF conduction path between an RF power subsystem and said electrode; a switch arrangement formed of an electrically conductive material, said switch arrangement and said RF conduction path structure having two relative positions relative to each other, a first relative position of said two relative positions being characterized by said switch arrangement being electrically coupled with said RF conduction path structure to provide a ground to said electrode, a second relative position of said two relative positions being characterized by said switch arrangement being electrically uncoupled from said RF conduction path; an insulator structure configured to interpose between said switch arrangement and said RF conduction path structure to result in said second relative position of said two relative positions; an actuator configured to move said insulator structure; and a heat sink configured to remove heat from said electrode and to mechanically support said actuator.
