Abstract:
A light spot arrangement, a surface profile measuring method and a method for calculating control data for an exposure field are disclosed. The light spot arrangement includes a plurality of measuring light spots ( 100 ) which define at least one set of orthogonal line segments, wherein the measuring light spots ( 100 ) lying on the orthogonal line segments radiate outward from a center, with each of the orthogonal line segments defined by at least four measuring light spots. The measuring light spots ( 100 ) are used to measure a profile of a planer surface. With this light spot arrangement comprising at least one set of orthogonal line segments defined by measuring light spots radiating outward from a center, readings of multiple ones of the light spots ( 100 ) can be acquired in real time, and exposure can be performed with real-time focusing and leveling based on a surface profile of the wafer ( 200 ) derived from a surface fitting process carried out on the readings. Specifically, during a scan performed by moving a wafer stage ( 300 ), readings of valid ones of the light spots are acquired as original surface profile data of the wafer ( 200 ), which are then processed to obtain leveling and focusing control data for the exposure field of the wafer stage ( 300 ).

Claim (Index 27):
The method for calculating control data for an exposure field of  claim 26 , further comprising, prior to step  3 , pre-processing of the original surface profile data, wherein the pre-processing includes removal of extreme values.
