    Abstract: The invention relates to a method for characterising and simulating a CMP process, according to which a substrate to be polished, in particular a semiconductor wafer is pressed onto a polishing cloth and rotated in relation to the latter for a specified polishing period. Said method comprises the following steps: a) determination of a set of process parameters, in particular of the contact force and the relative rotational speed of the substrate and the polishing cloth; b) provision and characterisation of a test substrate comprising test patterns with different structural thicknesses for the specified process parameters; c) determination of a set of model parameters for simulating the CMP process from the results of the characterisation of the test substrate; d) determination of layout parameters of the substrate to be polished; e) determination of a requirement profile relative to the CMP process result for the substrate to be polished; and f) simulation of the CMP processes for determining the polishing period necessary to fulfil the requirement profile. The invention also relates to a method for operating a test device for semiconductor components.

    Abstract: A chemical mechanical polishing process rotates a wafer having an alignment mark at a wafer rotation rate and a polishing surface at an off-matched rotation rate. The wafer rotation rate and the off-matched rotation rate are not equal. The wafer rotating at the wafer rotation rate and the polishing surface rotating at the off-matched rotation rate touch to polish a plurality of points on the wafer. The rotation of the wafer rotating at the wafer rotation rate is adjusted with respect to the polishing surface rotating at the off-matched rotation rate to achieve an approximately zero averaged rotation rate velocity for each of the points on the wafer with respect to the polishing surface polishing the wafer upon a completion of the total polishing time.
