Aluminum electrode on wafer UBM formation plating process
Plating chemicals, total proposals for surface treatment processes and equipment, aluminum electrodes on wafers, UBM formation, plating process.
UBM (Under Barrier Metal) employs electroless Ni/Au plating and electroless Ni/Pd/Au plating; however, conventional processes have faced challenges such as localized corrosion of aluminum electrodes, poor plating appearance, and adhesion issues. Additionally, in recent years, as power semiconductors have advanced towards higher voltage and higher current, there is an increasing demand for enhanced heat resistance in electroless plating films. In response, we have newly developed the "TORYZA EL PROCESS," a plating process for forming UBM on aluminum electrodes that suppresses film reduction and localized corrosion while exhibiting excellent uniform deposition, smoothness, and adhesion of electroless Ni plating. Along with the electroless plating equipment "TORYZA EL SYSTEM" for UBM formation, we offer a comprehensive proposal for plating chemicals, surface treatment processes, and equipment for semiconductor back-end processes.
