摘要:
A substrate attracting and holding method includes steps of supporting a substrate by use of a protrusion provided on a holding table for holding the substrate and reducing pressure between the holding table and the substrate to attract and hold the substrate. The protrusion is disposed to be placed in a predetermined positional relation, with respect to a direction along the surface of the substrate, with (i) a position of an alignment mark to be used for processing the substrate or (ii) a position to with respect to which an alignment mark is to be produced. The method also includes attracting and holding the substrate.
摘要:
An exposure method for scanning a master plate having a pattern and a photosensitive substrate relative to a projection optical system for projecting the pattern onto the substrate. The method includes a first step of accelerating a stage to a predetermined velocity, the stage holding the master plate or the substrate, a second step of transporting the stage at the predetermined velocity and exposing the substrate to the pattern during travel of the stage in a scanning direction, a third step of stopping the stage traveling at the predetermined velocity, and an acceleration step of accelerating the stage between the second step and the third step.

摘要:
An exposure apparatus for lithographically transferring a pattern of an original onto a substrate to be exposed includes a first detector for detecting a position of an alignment mark on an exposure shot formed on the substrate, a second detector for detecting a local tilt adjacent to the alignment mark, the position of which is detected by the first detector, and a third detector for detecting a tilt of the exposure shot.
摘要:
An exposure apparatus particularly suitable usable for the manufacture of semiconductor microcircuit is disclosed. The apparatus includes a specific arrangement that allows accurate and precise detection of any change in the imaging magnification and/or the image surface position of a projection optical system included in the projection exposure apparatus. Thus, with the present invention, a pattern can be projected upon a workpiece with improved accuracy.
