Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A system for forming a semiconductor structure, comprising:
a first chamber, configured to provide a first low-pressure environment for a hybrid bonding operation;
a second chamber, connected to the first chamber and configured to provide a second low-pressure environment having a pressure greater than a pressure of the first low-pressure environment;
a controller, configured to control the hybrid bonding operation;
a bonding apparatus, disposed in the first chamber and configured to provide a force on a central region of a semiconductor device gradually toward a peripheral region of the semiconductor device during the hybrid bonding operation; and
a first pump, connected to a first valve disposed on an inner sidewall of the first chamber, and configured to remove air from the first chamber prior to or during the hybrid bonding operation.
