Abstract:
1. A measurement method, of using a measurement system to measure a plurality of X marks and a plurality of Y marks as measurement objects formed on a prescribed substrate, comprising: a first process of setting a measurement condition for the measurement system to a first condition when measuring, with the measurement system, all of the X marks among the marks which are the measurement objects on the prescribed substrate without measuring the Y marks under the first condition, the X marks including all marks for measuring positions in a first direction in a two-dimensional place on the substrate, the Y marks including all marks for measuring positions in a second direction orthogonal to the first direction in the two-dimensional plane on the substrate; a second process, after measuring all of the X marks on the prescribed substrate under the first condition, of switching the measurement condition from the first condition and setting a second condition; and a third process of measuring, with the measurement system, all of the Y marks without measuring the X marks, under the second condition.
