ABSTRACT:
A holding device including a holding element, on which a substrate is electrostatically fixed, positioned on a substrate electrode. In one configuration, a load body on the substrate electrode presses the holding element onto it, and is connected via a clamping device, which presses the former onto the substrate electrode, with a base, which supports the substrate electrode, the load body and the base being electrically insulated from the substrate electrode. In another configuration, the side of the holding element faces the substrate as an electrically insulating ferroelectric or piezoelectric material. Another configuration includes a device via which a liquid convection medium is feedable into a space formed by the holding element and substrate or is removable from there again. A method for supplying heat or dissipating heat from the back of a substrate to which heat is applied from the front, and which is held by the holding device.
