Puncture resistant electrostatic chuck |
abstract |
A puncture resistant electrostatic chuck (20) is described. Thenchuck (20) comprises at least one electrode (25) ; and a composite insulatorn (30) covering the electrode. The composite insulator comprises a matrixnmaterial having a conformal holding surface (50) capable of conforming tonthe substrate (35) under application of an electrostatic force generated bynthe electrode to reduce leakage of heat transfer fluid held between thensubstrate and the holding surface. A hard puncture resistant layer, such anlayer of fibers or an aromatic polyamide layer, is positioned below the holdingnsurface (50) and is sufficiently hard to increase the puncture resistance ofnthe composite insulator. |
