A method and apparatus for mapping depth of an object (22) in a preferred arrangement uses a projected light pattern to provide a selected texture to the object (22) along the optical axis (24) of observation. An imaging system senses (32, 34) first and second images of the object (22) with the projected light pattern and compares the defocused of the projected pattern in the images to determine relative depth of elemental portions of the object (22).

In a method for manufacturing semiconductor devices and other finely structured parts, a projection objective (5) is used in order to project the image of a pattern arranged in the object plane of the projection objective onto a photosensitive substrate which is arranged in the region of the image plane (12) of the projection objective. In this case, there is set between an exit surface (15), assigned to the projection objective, for exposing light and an incoupling surface (11), assigned to the substrate, for exposing light a small finite working distance (16) which is at least temporarily smaller in size and exposure time interval than a maximum extent of an optical near field of the light emerging from the exit surface. As a result, projection objectives with very high numerical apertures in the region of NA>0.8 or more can be rendered useful for contactless projection lithography.

Methods for performing a scheme that results in a refined measurement pattern within an optical grid are provided. Physically adjusting spacing of elements within an optical grid to achieve enhanced resolution is historically unfeasible, as reduction of the spacing causes light sensors of the optical grid to pick up false signals when reading light beams. Technology introduced by the present invention generates a virtual reduced spacing of the elements within the optical grid by using two signals that are slightly different. These slightly different signals can accomplish, at least, quarter-grid spacing resolution within the optical grid. Additionally, the enhanced resolution derived from the virtual reduced spacing is employed to govern movement of a motor. The motor movement is in response to one or more changes of direction such that the motor is operating in its linear range. Advantageously, the virtual reduced spacing allows for substantial movement in a non-linear phase, while only limited movement in a linear phase is necessary to locate accurately a target within the optical grid.
