UBM formation plating process for aluminum electrodes on a wafer.
It is the process of forming UBM. It can improve the connection reliability between the aluminum electrode and the package terminal.
UBM stands for Under Bump Metal or Under Barrier Metal, and it is a film formed to join aluminum electrode pads on semiconductor chips with package terminals through wire bonding, soldering, or silver sintering. This film is composed of materials such as electroless nickel/gold plating or electroless nickel/palladium/gold plating. We offer a wide range of products that support the evolution of semiconductors and electronics, so please feel free to consult with us.
