1. A method of manufacturing an electrostatic chuck, the method comprising:
preparing a powdered composite material by ball-milling (i) aluminum or aluminum alloy powder and (ii) carbon-based nanomaterial powder;
preparing an electrode layer by subjecting the powdered composite material to spark plasma sintering (SPS);
forming a metal layer at least partially over the electrode layer, the metal layer comprising 1% to 5% by weight of cobalt (Co), 10% to 20% by weight of nickel (Ni), and 75% to 85% by weight of iron (Fe); and
forming a dielectric layer at least partially over the electrode layer and the metal layer.
