Patent ID: 11398398

Abstract:
Holding apparatus 100 for electrostatic holding of component 1, in particular a silicon wafer, includes plate-type base body 10 with plurality of projecting burls 11, the front surfaces 12 of which span a burl support plane for component 1, and electrode device 20 arranged in layered form in spacings between burls 11 and has plastic insulating layer 21 connected with base body 10, electrode layer 22 and dielectric layer 23, whereby electrode layer 22 is arranged between insulating layer 21 and dielectric layer 23, whereby a predetermined gap spacing A is set between the burl support plane and a top side of dielectric layer 23, and dielectric layer 23 includes an inorganic dielectric and is embedded at least in part into insulating layer 21. Methods for producing holding apparatus 100 for electrostatic holding of component 1, in particular a silicon wafer, are also described.
