Abstract:
This document describes a method of determining an overlay error during manufacturing of a multilayer semiconductor device. Manufacturing of the semiconductor device comprises forming a stack of material layers comprising depositing of at least two subsequent patterned layers of semiconductor material, the patterned layers comprising a first patterned layer having a first marker element and a second patterned layer having a second marker element. The determining of the overlay error comprises determining relative positions of the first and second marker element in relation to each other, such as to determine the overlay error between the first patterned layer and the second patterned layer. In addition an imaging step is performed on at least one of said first and second patterned layer, for determining relative positions of the respective first or second marker element and a pattern feature of a device pattern comprised by said respective first and second patterned layer.

Claim (Index 13):
System according to  claim 12 , comprising a sensor head including a probe with a cone shaped probe tip for scanning of a surface of the at least one first or second patterned layer for performing said scanning probe microscopy, wherein the sensor head is arranged for tilting of the cone shaped probe tip such that an apex of the cone shaped probe tip forms a foremost point in a scanning direction during scanning.
