A high temperature substrate coating to mitigate liquid metal embrittlement (LME) cracking in automobile vehicles includes a substrate. A coating is disposed on the substrate, the coating being one of a zinc-based material and an aluminum-based material, with the coating having a melting point of at least 500° C.

Aspects are directed to a reference electrode integrated on a surface of a substrate to facilitate functionalization of a working electrode. The reference electrode is used in the electrochemical deposition or electrodeposition of one or more functional layers on a working electrode. The working electrode may be a sensing element of an analyte-selective sensor. Additional aspects of the current subject matter are directed to a counter electrode integrated on a surface of a substrate.

There is provided a substrate holder for holding a substrate including a first holding member having a first opening portion for exposing a first surface of the substrate, and a second holding member configured to hold the substrate together with the first holding member and having a second opening portion for exposing a second surface of the substrate, wherein the first holding member has at least one first external connection contact, and the second holding member has at least one second external connection contact that is independent of the first external connection contact.

The workpiece holding jig includes a first frame body and a second frame body, both frame bodies each have a body, a conductive member, a contact member provided so as to be able to come into electrical contact with a periphery of a workpiece, and an inner circumferential seal member provided over an entire circumference of the body. Both frame bodies are configured to constitute a seal space for accommodating the periphery of the workpiece, the conductive member of both frame bodies, and the contact member of both frame bodies, in a state where each of the inner circumferential seal members and the contact member abut against the periphery of the workpiece from both sides. The inner circumferential seal member has a contact projection, and an inner surface of the contact projection is slanted outward.

An electrochemical deposition system configured for electrochemical plating of a substrate includes a chamber, an electrode, a plating cup and a controller. The chamber holds a plating bath. The electrode is disposed in the plating bath. The plating cup includes a contact ring. The contact ring includes contacts. The contacts are immersed in the plating bath. The controller is configured to apply a voltage signal across the contact ring and the electrode to remove residual from the contacts. The voltage signal includes a plating-de-plating waveform. The plating-de-plating waveform includes multiple cycles. Each of the cycles includes a pair of pulses with different polarity.

The receiver is coupled to the arm and configured to receive the cleaning agent after the cleaning agent is sprayed onto the substrate holder.

The present invention discloses a device and method for preventing copper plating of a conductor roll in the technical field of manufacturing of copper electroplating films. A conductor roll and an electroplating anode are respectively connected to the negative output end and the positive output end of a first power source, the conductor roll and the electroplating anode electroplate a plating product flowing through plating pool bath after being electrified, and the conductor roll is connected to the positive output end of a second power source and mated with an auxiliary electrode connected to the negative output end of the second power source to realize the electrolysis of the conductor roll so that the conductor roll avoids copper deposition when electroplating the plating product. The present invention can realize the electrolysis of bath near the conductor roll on the premise of completing electroplating by the conductor roll so that the copper electroplating process and the copper electrolyzing process are balanced on the conductor roll to avoid residual copper on the conductor roll so as to improve the copper plating quality of the plating product, and the present invention does not increase the procedure of the electroplating process or affect the implementation of the electroplating process.
