Abstract:
An alignment system ( 100 ) and method for positioning and/or keeping a first object ( 1 ) at a controlled distanced (D 1 ) with respect to a second object ( 2 ). An object stage ( 11 ) is configured to hold a surface ( 1 a ) of the first object ( 1 ) at a distance (D 1 ) over a surface ( 2 a ) of the second object ( 2 ). A sensor device ( 31 ) comprising a probe tip ( 31 a ) is connected at a predetermined probe level distance (Dp) relative to the surface ( 1 a ) of the first object ( 1 ). The probe tip ( 31 a ) is configured to perform an atomic force measurement (AFM) of a force (F 1 ) exerted via the probe tip ( 31 a ) on a surface ( 2 a ) of the second object ( 2 ). A controller ( 80 ) is configured to control an object stage actuator ( 21 ) as a function of the probe level distance (Dp) and the measured force (F 1 ) to maintain the controlled distanced (D 1 ).

Claim (Index 5):
The system according to  claim 1 , wherein the system comprises a distance sensing arrangement configured to directly measure a distance between a first position (P 1 ) that is fixed relative to the first object and/or object stage, and a second position (P 2 ) that is fixed relative to the sensor device and/or sensor stage, wherein the system comprises a light guide configured to direct a light beam (L 2 ) from a light source along a light path to a light sensor, wherein the light path traverses the first and second positions (P 1 , P 2 ), wherein the system is configured to perform an interferometric measurement of the light beam (L 2 ) to measure a change of the distance between the first and second positions (P 1 , P 2 ).
