ABSTRACT:
The invention relates to a lifting and supporting device for handling and positioning particularly large-surface elements in the shape of panels, especially in plasma processing installations. Said lifting and supporting device comprises a particularly metallic base plate, on which a plurality of particularly dielectric pins are arranged. Said pins may be set in pin holes especially provided in the base plate. Said panel-shaped element may be positioned on the pin end for the handling thereof or during a plasma processing. Said panel-shaped element may present an electrostatic charge. A small diameter for the pins and pin holes is selected such that, in conformity with the panel-shaped element provided with the electrostatic charge, an undesired electrostatic charge on said panel-shaped element is essentially avoided or, in conformity with the panel-shaped element to be plasma processed, a plasma perturbation in the area of the pin holes or pins is essentially avoided.
