Abstract
A method for utilizing a probe card includes steps as follows. Providing a probe card having three alignment marks on a reference plane of a circuit board; moving the circuit board to be oriented to a wafer-loading plane of a wafer stage with the reference plane; determining whether a geometric plane defined by the alignment marks is parallel to the wafer-loading plane; and when the geometric plane is not parallel to the wafer-loading plane, adjusting a levelness of the circuit board until the reference plane is parallel to the wafer-loading plane.
