Abstract
An alignment method and an alignment device thereof are provided. The alignment method includes: providing a wafer including wafer coordinate information. Two probes are respectively aligned with two bonding pads on a dicing road of the wafer, and an image capture device is used to assist the two probes to obtain actual wafer information. The wafer coordinate information is then compared with the actual wafer information to determine whether the two probes are accurately aligned with the two bonding pads on the dicing road, respectively. When an alignment position of the two probes is determined, the positions of any chips and bonding pads on the wafer can be determined.
