Detachable electrostatic chuck having sealing assembly
摘要:
A detachable electrostatic chuck is capable of being attached to a pedestal in a process chamber. The chuck comprises an electrostatic puck having a ceramic body with an embedded electrode. The chuck also has a baseplate below the electrostatic puck with a lower surface which is bonded to a sealing assembly comprising a sealing plate and sealing ring. The sealing plate and ring are polished to form a gas-tight seal between the chuck and pedestal to prevent gas leakage from or into this region.
