Abstract: The physical vapor deposition (PVD) sputtering system is one of the key process equipment for panel-level advanced packaging, and its performance directly affects packaging quality and reliability. A sputtering system designed for large-size (510 mm×515 mm and above) panel-level advanced packaging is introduced. The system is equipped with multiple unit modules, enabling continuous automated sputter coating production while reducing process costs. The self-developed large-size cathode sputtering system effectively improves the deposition rate and increases target utilization to 50%. The self-developed cooling system significantly reduces substrate surface temperature, mitigates warpage, and achieves finer control. The non-uniformity of Ti and Cu film deposited on 510 mm×515 mm substrates is ±3.05% and ±2.36%, respectively. The adhesion strength of Ti/Cu films on glass substrates reaches 277 N/cm2, reducing risks such as seed layer delamination. The entire process is completed within a vacuum system, minimizing contamination of substrates from moisture and particles. These findings provide crucial reference and guidance for panel-level advanced packaging technologies.

Key words: panel-level advanced packaging, physical vapor deposition, seed layer, large-size planar sputtering cathode system
