摘要:
A method for determining the focal position of at least two edges of structures (31) on a substrate (30) is disclosed. During the movement of a measurement objective (21) in the Z-coordinate direction, a plurality of images of the at least one structure (31) is acquired with at least one measurement window (45) of a detector. An intensity profile of the structure (31) is determined for each image.

A system and a method for determining positions of structures on a substrate are disclosed. The system includes at least one measurement table (20) movable in the X-coordinate direction and in the Y-coordinate direction, a measurement objective (9) and a camera for determining the positions of the structures (3) on the substrate (2). The position of the measurement objective (9) and/or the measurement table (20) may be determined by at least one interferometer (24). The system is surrounded by a housing representing a climatic chamber (50) provided with an active pressure regulation.

摘要:
A method and a measuring instrument for determining the position of an edge to be measured on a pattern on a substrate are described. A complete, nonlinear model intensity profile, which identifies the edge to be measured, of a model edge is ascertained and stored, and a desired edge position xk is defined therein with subpixel accuracy. A camera image of the substrate having the edge to be measured is acquired, and a one-dimensional measured intensity profile of the edge to be measured is determined therefrom. The model intensity profile is identified in the measured intensity profile with an indication of its location xm relative to a reference point. The desired position p of the edge to be measured is determined with subpixel accuracy as p=xm+xk.
