  • Publication number: 20240347370
    Abstract: A carrier dechucking system includes a work carrier including a substrate having a first surface, an opposite second surface with a support film attached, and a ring frame surrounding the substrate. The work carrier is placed on a placement table having a support surface on which a lower surface of the support film is maintained, lifting pins configured to move the work carrier, an ionizer configured to eject ions to the lower surface, and a controller. The controller is configured to control the lifting pins to move the work carrier from the support surface to first and second levels, and to control the ionizer to remove static electricity charged on the support film from the support surface to the first level. At the first level, a surface voltage of the first surface of the substrate is lower than a surface voltage of the lower surface of the support film.

  • Publication number: 20230178345
    Abstract: A chamber cleaning method includes processing a wafer for a Cu-to-Cu bonding process using plasma in a chamber; and removing copper from the chamber. Removing copper includes forming copper oxide on an inner wall of the chamber by oxidizing copper in the chamber by a plasma treatment that uses a first gas, performing a first monitoring operation that monitors a copper contamination state in the chamber using an optical diagnostic method, removing the copper oxide by a plasma treatment that uses a second gas; and performing a second monitoring operation that monitors a copper contamination state in the chamber using the optical diagnostic method.

  • Patent number: 11581202
    Abstract: A substrate debonding apparatus configured to separate a support substrate attached to a first surface of a device substrate by an adhesive layer, the substrate debonding apparatus including a substrate chuck configured to support a second surface of the device substrate, the second surface being opposite to the first surface of the device substrate; a light irradiator configured to irradiate light to an inside of the adhesive layer; and a mask between the substrate chuck and the light irradiator, the mask including an opening through which an upper portion of the support substrate is exposed, and a first cooling passage or a second cooling passage, the first cooling passage being configured to provide a path in which a coolant is flowable, the second cooling passage being configured to provide a path in which air is flowable and to provide part of the air to a central portion of the opening.

  • Patent number: 9640507
    Abstract: A bonding method for bonding a semiconductor chip to an underlying structure includes aligning an electrical contact of a lower surface of the semiconductor chip with an electrical connection member of an upper surface of the underlying structure, the electrical contact at least partially encased by a support material. The method further includes first heating the semiconductor chip and the underlying structure, deforming the electrical contact, and curing the support material encasing the deformed electrical contact. The method still further includes second heating the semiconductor chip and the underlying structure to bond the electrical contact of the semiconductor chip to the electrical connection member of the underlying structure while maintaining the support material in a cured state.

  • Publication number: 20130248114
    Abstract: A bonding apparatus includes at least one stage unit to support a circuit board having a chip thereon and a bonding unit coupled to the stage unit to define a chamber. The bonding unit has at least one inductive heater to heat to bond the chip to the circuit board, and the stage unit includes a vacuum generator configured to generate a vacuum between the stage unit and the circuit board. The vacuum is used to hold the circuit board on the stage unit during bonding of the chip to the circuit board. The induction heater may include one or more induction heating antennas, and the chamber may include one or more stage units.
