Patent ID: 7133273

Claim:
Device for electrostatically holding a wafer ( 2 ), comprising: a rigid flat metal support ( 4 ), at least one electrode ( 8 ) associated with a remote electrical energy supply, the electrode being supported by one surface of the flat support ( 4 ) and confined between two sheets ( 6 , 10 ) of an insulating material, another surface of the support ( 4 ) being flat and adapted to hold the wafer, and a handle member ( 24 ) with a securement device ( 22 ) that attaches the handle member to the support, the handle member including connections ( 26 , 28 ) that are adapted to connect the electrode ( 8 ) to the remote electrical energy supply, wherein the electrode ( 8 ) has a U shape with two branches and a base, the base having two separate tongues ( 16 , 18 ) that are each connected to a respective one of the connections ( 26 , 28 ), and wherein each of the two branches has extensions of both the two separate tongues therein.
