Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method of manufacturing a semiconductor device, the method comprising:
forming a bonded substrate by bonding a carrier substrate to a semiconductor substrate in a bonding part of a semiconductor packaging apparatus;
performing a cooling process that cools the bonded substrate; and
detecting, by a detection part of the semiconductor packaging apparatus, a defect of the bonded substrate during the cooling process,
wherein detecting the defect of the bonded substrate comprises detecting by the detection part of the semiconductor packaging apparatus, misalignment between the semiconductor substrate and the carrier substrate,
wherein detecting the misalignment comprises obtaining edge images of an upper surface of the bonded substrate,
wherein detecting the misalignment by the detection part of the semiconductor packaging apparatus comprises obtaining a degree of the misalignment between the semiconductor substrate and the carrier substrate using the edge images,
wherein obtaining the degree of the misalignment comprises:
yielding edge offset values from the edge images, wherein each of the edge offset values corresponds to a respective degree that an edge of the carrier substrate is offset from an edge of the semiconductor substrate.
