Abstract: A device for high-precision machining of the surface of an object, such as for polishing and lapping semiconductor substrates, in which the object is held on an accommodation surface for its machining. The accommodation surface can be deformed by means of a actuators connected to the surface in a positive-lock and/or non-positive-lock manner. The actuators are provided between a base plate and an accommodation plate that are mechanically biased relative to one another. The accommodation plate is configured, on its inside, with concentric grooves forming rigid rings in the axial direction. The individual rings are connected by solid substance joints. Piezo-stacks configured as actuator-sensor elements, as well as springs, are disposed between the faces of the rings and the base plates and are offset relative to one another by 120°.

Abstract: The aim the invention is to machine the surface of objects using a universal device as economically as possible and in a significantly reduced amount of time, even in the event of process variations, material non-homogeneities etc., with high reproducible precision. The this end, the pressure distribution on the surface which is decisive for the machining process is determined by temporarily weighting the object to be machined—said object being fixed to a receiving surface (17)—and measuring the thus occurring change in position of the receiving surface (17) by means of actuator-sensor elements (180 from the calculated pressure distribution. The invention can generally be applied to the surface machining of objects beyond the lapping or polishing of the above-mentioned semiconductor substrates.
