BONDING DEVICE AND BONDING METHOD
First Claim
1. A bonding device for bonding substrates together, comprising:
- a first holding unit configured to hold a first substrate on a lower surface of the first holding unit;
a second holding unit located below the first holding unit and configured to hold a second substrate on an upper surface of the second holding unit;
a moving mechanism configured to move the first holding unit or the second holding unit in a horizontal direction and a vertical direction;
a first image pickup unit located in the first holding unit and configured to pick up an image of the second substrate held in the second holding unit; and
a second image pickup unit located in the second holding unit and configured to pick up an image of the first substrate held in the first holding unit,at least one of the first image pickup unit and the second image pickup unit including an infrared camera.

7. A bonding method for bonding substrates with a bonding device which includes a first holding unit configured to hold a first substrate on a lower surface of the first holding unit, a second holding unit located below the first holding unit and configured to hold a second substrate on an upper surface of the second holding unit, a moving mechanism configured to move the first holding unit or the second holding unit in a horizontal direction and a vertical direction, a first image pickup unit located in the first holding unit and configured to pick up an image of the second substrate held in the second holding unit, and a second image pickup unit located in the second holding unit and configured to pick up an image of the first substrate held in the first holding unit, at least one of the first image pickup unit and the second image pickup unit including an infrared camera, the method comprising:
-
picking up images of the second substrate not yet bonded and the first substrate not yet bonded by the first image pickup unit and the second image pickup unit, respectively; and adjusting horizontal positions of the first holding unit and the second holding unit by the moving mechanism based on the images thus picked up. - View Dependent Claims (8, 9, 10, 14)

11. A bonding method for bonding substrates with a bonding device which includes a first holding unit configured to hold a first substrate on a lower surface of the first holding unit, a second holding unit located below the first holding unit and configured to hold a second substrate on an upper surface of the second holding unit, a moving mechanism configured to move the first holding unit or the second holding unit in a horizontal direction and a vertical direction, a first image pickup unit located in the first holding unit and configured to pick up an image of the second substrate held in the second holding unit, and a second image pickup unit located in the second holding unit and configured to pick up an image of the first substrate held in the first holding unit, at least one of the first image pickup unit and the second image pickup unit including an infrared camera, the method comprising:
-
obtaining an image for inspection of an overlapped substrate obtained by bonding the first substrate and the second substrate using the infrared camera; and adjusting horizontal positions of the first holding unit and the second holding unit with the moving mechanism based on the image for inspection obtained from the infrared camera. - View Dependent Claims (12, 13, 15)
