摘要： The present invention provides a method for calculating a corrected substrate height map of a first substrate using a height level sensor. The method comprises: sampling the first substrate by means of the height level sensor with the first substrate moving with a first velocity, wherein the first velocity is a first at least partially non-constant velocity of the first substrate with respect to the height level sensor, to generate a first height level data, generating a first height map based on the first height level data, and calculating a corrected substrate height map by subtracting a correction map from the first height map, wherein the correction map is calculated from the difference between a first velocity height map and a second velocity height map.

摘要： A method of processing a data set including equispaced and/or non-equispaced data samples is disclosed. The method includes filtering of the data, wherein a kernel defined by a probability density function is convoluted over samples in the data set to perform a weighted average of the samples at a plurality of positions across the data set, and wherein a first order regression is applied to the filtered data to provide a processed data output.

摘要： Systems, apparatuses, and methods are provided for generating level data. An example method can include receiving first level data for a first region of a substrate. The first region can include a first subregion having a first surface level, and a second subregion having a second surface level. The example method can further include generating, based on the first level data, measurement control map data. The example method can further include generating, based on the measurement control map data, second level data for a second region of the substrate. The second region can include a plurality of third subregions each having a third surface level equal to about the first surface level, and, optionally, no region having a surface level equal to about the second surface level.

摘要： An apparatus for measuring a height of a substrate for processing in a lithographic apparatus is disclosed. The apparatus comprises a first sensor for sensing a height of the substrate over a first area. The apparatus also comprises a second sensor for sensing a height of the substrate over a second area. The apparatus further comprises a processor adapted to normalize first data corresponding to a signal from the first sensor with a second sensor footprint to produce a first normalized height data, and to normalize second data corresponding to a signal from the second sensor with a first sensor footprint to produce a second normalized height data. The processor is adapted to determine a correction to a measured height of the substrate based on a difference between the first and second normalized height data.
