摘要: An electrostatic chuck for holding a substrate has an electrostatic member having a dielectric covering an electrode that is chargeable to electrostatically hold the substrate. The bond layer has a metal layer that is infiltrated or brazed between the electrostatic member and the base. The base may be a composite of a ceramic and metal, the composite having a coefficient of thermal expansion within about null30% of a coefficient of thermal expansion of the electrostatic member. The base may also have a heater.
