Abstract: The invention includes a puncture-resistant electrostatic chuck with a flat surface and a method of making the same. The electrostatic chuck includes a conductive layer such as copper foil that is laminated to a first insulation layer such as a polyimide. A puncture-resistant layer is placed over the conductive layer and includes random or woven fibers held together by a resin. The puncture-resistant layer has an uneven topography on a top surface due to the fibers contained therein. A second insulation layer overlies the puncture-resistant layer and has a top surface which is substantially flat. The flat top surface of the second insulation layer is made by laminating layers together with a mandrel which is polished and free of irregularities such as pits, dents and high spots. Preferably the mandrel has a uniform thickness over its entire surface.
