Disclosed are apparatus, systems, and methods for electroplating cobalt, nickel, and alloys thereof in interconnect features of partially or fully fabricated electronic devices. During electroplating, cobalt, nickel, or alloys thereof fill features by a bottom up electrofill mechanism. Examples of features that may be electrofilled with cobalt, nickel, or alloys thereof include micro TSVs, contacts for devices, and certain gates for transistors. Electroplating apparatus may include electroplating cells along with one or more instances of each of a post-electrofill module, an anneal chamber, a plasma pretreatment module, and a substrate pre-wetting module.

A method of controlling chemical concentration in electrolyte includes measuring a chemical concentration in an electrolyte, wherein the electrolyte is contained in a tank; and increasing a vapor flux through an exhaust pipe connected to the tank when the measured chemical concentration is lower than a control lower limit value.

A portable electroplating system with components integrated into a complete system, rather than separated and disjointed. A single electroplating system can be self-contained to include all necessary rectifiers, tanks, cleaning functionalities, and other helpful or necessary items. By using smaller components than conventional electroplating systems, the system can allow for more economical use of chemicals, solutions, and energy and can be utilized more efficiently towards a unique shape or size of object to be plated. The system can also include wheels to make the system portable. A rack management system can be employed to move objects from one location to another within the system.

Systems for cleaning electroplating system components may include a seal cleaning assembly incorporated with an electroplating system. The seal cleaning assembly may include an arm pivotable between a first position and a second position. The arm may be rotatable about a central axis of the arm. The seal cleaning assembly may include a cleaning head coupled with a distal portion of the arm. The cleaning head may include a bracket having a faceplate coupled with the arm, and a housing extending from the faceplate. The housing may define one or more arcuate channels extending through the housing to a front surface of the bracket. The cleaning head may also include a rotatable cartridge extending from the housing of the bracket. The cartridge may include a mount cylinder defining one or more apertures configured to deliver a cleaning solution to a pad coupled about the mount cylinder.

The present invention belongs to the technical field of shoe spikes, and more particularly relates to a carborundum wear-resistant shoe spike. The carborundum wear-resistant shoe spike comprises a shoe spike main body and a nickel coating attached to the surface of the shoe spike main body; the surface of the shoe spike main body is also provided with a carborundum layer, and the nickel coating is disposed between the shoe spike main body and the carborundum layer. Compared with the prior art, the present invention lies in that the outer surface of the nickel coating is provided with the carborundum layer, and since the carborundum layer has the characteristics of good toughness, high hardness, good wear resistance and the like, the wear resistance property of the shoe spike can be greatly improved, and the service life of sports shoes using the shoe spike is prolonged.
