    摘要: In a plating apparatus including a shielding member, an ionically resistive element is disposed to be close to a surface to be plated of a substrate to improve uniformity of a distribution of plating film-thickness.
    A plating apparatus includes: a plating tank 410 configured to house a plating solution; a substrate holder 440 configured to hold a substrate Wf with a surface to be plated Wf-a facing downward; an anode 430 disposed in the plating tank 410; an ionically resistive element 450 disposed between the substrate Wf and the anode 430 and including an opposed surface 450-a opposed to the surface to be plated Wf-a, the opposed surface 450-a including a first opposed surface 450-a1 and a second opposed surface 450-a2 apart from the surface to be plated Wf-a more than the first opposed surface 450-a1; and a shielding member 481 disposed in a depressed region β of the ionically resistive element 450, the depressed region β being formed by the second opposed surface 450-a2. The shielding member 481 is for shielding an electric field.

    摘要: An objective of the present invention is to provide a plating apparatus capable of improving uniformity of a plating film formed on a substrate. The plating apparatus includes a plating tank, a substrate holder that holds a substrate, an anode disposed, in the plating tank, facing the substrate held by the substrate holder, and a film thickness measuring module including a sensor that detects a parameter related to a plating film formed on a surface to be plated of the substrate, the film thickness measuring module measuring a film thickness of the plating film based on a detection value of the sensor during a plating treatment.

    摘要: Provided is a technique that allows removing gas bubbles attached to a hole of an ionically resistive element.
    A plating method includes: stirring a plating solution by driving a paddle arranged above the ionically resistive element in a state where an anode and the ionically resistive element are immersed in the plating solution (step S20); immersing a substrate as a cathode in the plating solution in a state where the stirring of the plating solution with the paddle is stopped (step S40); resuming the stirring of the plating solution with the paddle arranged above the ionically resistive element and below the substrate in a state where the substrate is immersed in the plating solution (step S50); and performing a plating process on the substrate by flowing electricity between the substrate and the anode in a state where the stirring of the plating solution with the paddle is resumed (step S60).

    摘要: There is provided a method of adjusting a plating module, wherein the plating module comprises a substrate holder configured to hold a substrate, an anode placed to be opposed to the substrate holder, and a plate placed between the substrate holder and the anode to serve as an ionically resistive element. The method comprises: providing a plating module of initial setting, which is initially set in such a state that a porosity in an outer circumferential portion of the plate is adjusted to reduce a plating film thickness in an outer circumferential portion of the substrate to be smaller than a film thickness in another portion; and adjusting a distance between the substrate holder and the plate so as to flatten a distribution of plating film thickness of the entire substrate by adjustment of the distance between the substrate holder and the plate such as to increase a film thickness in the outer circumferential portion of the substrate according to a film thickness distribution of the substrate that is plated in the plating module.

    摘要: Provided is a technique that allows suppressing an entrance of a large amount of a rinse solution into a plating solution in a plating tank.
    A plating apparatus 1000 includes a rinse module 40 configured to perform a rinse process. The rinse module includes: a rinse nozzle 41 configured to discharge the rinse solution to a member to be rinsed 25 while the rinse process is performed; a blow nozzle 42 disposed below the rinse nozzle and blowing out a gas such that the gas crosses a space between the plating tank and a substrate holder 20 while the rinse process is performed; and a collection member 50 disposed at downstream of the gas blown out from the blow nozzle and collecting the rinse solution dropping from the member to be rinsed and entrained in a flow of the gas blown out from the blow nozzle.

    摘要: Systems and methods for electroplating are described. The electroplating system may include a vessel configured to hold a first portion of a liquid electrolyte. The system may also include a substrate holder configured for holding a substrate in the vessel. The system may further include a first reservoir in fluid communication with the vessel. In addition, the system may include a second reservoir in fluid communication with the vessel. Furthermore, the system may include a first mechanism configured to expel a second portion of the liquid electrolyte from the first reservoir into the vessel. The system may also include a second mechanism configured to take in a third potion of the liquid electrolyte from the vessel into the second reservoir when the second portion of the liquid electrolyte is expelled from the first reservoir. Methods may include oscillating flow of the electrolyte within the vessel.
