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.
