Verfahren zur Bestimmung geometrischer Parameter eines Wafers und Verwendung des Verfahren bei der optischen Inspektion von Wafern

A method of determining geometric parameters of a wafer ( 16 ) is disclosed. For this purpose, the wafer ( 16 ) is inserted in a wafer holder ( 30 ). The wafer holder ( 30 ) is equipped with at least three mechanical contacting elements ( 22 ). The wafer is in mechanical contact with the contacting...
