    摘要: A failure resistant electrostatic chuck 20 for holding a substrate 35 during processing of the substrate 35 comprises one or more electrodes 25 covered by an insulator 30, the electrodes 25 capable of electrostatically holding a substrate 35 when a voltage is applied thereto. An electrical power bus 40 comprises one or more output terminals 45 that conduct voltage to the electrodes 25. The fuses 50 are positioned in hollow cavities 55 in the insulator 30, and electrically connect the electrodes 25 in series to the output terminals 45 of the power bus 40. Each fuse 50 can electrically disconnect an electrode 25 from an output terminal 45 when the insulator 30 covering the electrode 25 punctures and exposes the electrode 25 to a plasma process environment thereby causing a plasma current discharge to flow through the fuse 50.

    摘要: In one embodiment, the invention is a guard ring for reducing particle entrapment along a moveable shaft of a substrate support. In one embodiment, the guard ring comprises a substantially annular guard ring positioned within a step formed in a sleeve that circumscribes the shaft. The guard ring is positioned to substantially seal a gap separating the shaft from the sleeve, so that the amount of particles and foreign matter that travel within or become trapped in the gap is substantially reduced. In another embodiment, a guard ring comprises a base portion having an inner perimeter and an outer perimeter, a first flange coupled to the inner perimeter, a second flange coupled to the outer perimeter, and a continuous channel separating the first flange from the second flange. The first flange is adapted to function as a spring that accommodates displacement of the shaft.
