Abstract
Method of manufacturing holding plate () including ceramic material of several chemical elements and configured for holding apparatus () for holding a component by electrostatic forces or vacuum, includes the steps of material removal from holding plate () by laser ablation, wherein by laser irradiation () protrusions () are formed on holding plate (), end faces () of which span a carrier surface for the component, and surface modification of holding plate () by laser irradiation (), wherein irradiation parameters of laser irradiation () are set such that at least one of the chemical elements of the ceramic material is enriched on the surface of holding plate (). A method is also described of manufacturing holding apparatus () for holding a component by electrostatic forces or vacuum, holding plate () which is produced with the inventive method, and holding apparatus () with at least one holding plate ().
