Abstract:
The present invention relates to an apparatus and a method for simultaneously performing delamination and adhesion processes. The apparatus which simultaneously performs delamination and adhesion processes includes: a lower stage configured to suction and fix a carrier substrate on which a first workpiece is adhered; and an upper stage including a curved main body configured to suction and fix a second workpiece and formed in a shape convex toward the first workpiece, and a driving portion configured to rotate the curved main body such that predetermined portions of the second workpiece sequentially come into contact with corresponding predetermined portions of the first workpiece at a predetermined pressure, adhere the second workpiece to the first workpiece, and delaminate the first workpiece from the carrier substrate during an adhesion process. According to the present invention, the required number of detailed processes and a process time are decreased, a yield is increased, and deformation of a workpiece due to a residual stress generated during the adhesion and delamination processes is minimized by the adhesion and delamination processes being performed simultaneously.

Claim (Index 1):
An apparatus for simultaneously performing delamination and adhesion processes, comprising:\n a lower stage configured to suction and fix a carrier substrate on which a first workpiece is adhered; and an upper stage including a curved main body configured to suction and fix a second workpiece and formed in a shape convex toward the first workpiece, and a driving portion configured to rotate the curved main body such that predetermined portions of the second workpiece sequentially come into contact with corresponding predetermined portions of the first workpiece at a predetermined pressure, adhere the second workpiece to the first workpiece, and delaminate the first workpiece from the carrier substrate during an adhesion process, wherein, after an adhered laminate is formed by adhering the second workpiece to the first workpiece, the adhered laminate is adsorbed on a curved surface of the curved main body, immediately after the adhered laminate is adsorbed on the curved surface of the curved main body, the curved main body is rotated in a direction opposite a rotational direction of the curved main body during the adhesion process such that the adhered laminate sequentially comes into contact with the carrier substrate at a predetermined pressure at the same time that an adsorption force of the curved surface is decreased to stack the adhered laminate on the carrier substrate, an upper suction force by which the upper stage suctions the second workpiece is stronger than a lower suction force by which the lower stage suctions the first workpiece, at least one of the first workpiece and the second workpiece includes a surface having an adhesive force and located opposite a suction surface, and the upper suction force and the lower suction force are weaker than an adhesive force between the first workpiece and the second workpiece.
