Patent ID: 7299545

Claim:
An alignment method for positioning objects to be bonded to each other by reading a positioning recognition mark provided on at least one object by movable recognition means, said alignment method comprising the steps of: moving one object to a position at which a recognition mark on the one object can be read simultaneously by said moveable recognition means with a recognition mark provided on the other object when the recognition marks of both objects are provided at positions that cannot be read simultaneously by said moveable recognition means; reading the recognition marks simultaneously during movement of the recognition means before its complete stop; and identifying an absolute position of the recognition mark by correcting a mark recognition position having been read by the recognition means, based on a position feedback signal of the recognition means sent during movement of the recognition means, wherein said step of identifying is done by correction in consideration of an amount of the movement after both recognition marks are simultaneously read, and wherein said step of identifying is done before complete stop of a table for moving the one object, based on a position feedback signal of the table when the one object is moved to the position to be read simultaneously by said movable recognition means.
