Statement of Work and Project Statement


Wafer Level Packaging (WLP) and the movement to Panel Level Packaging (PLP) have gained industry attention as more cost-effective packaging technology for certain applications.  In both cases the molding poses technical challenges in terms of understanding the optimum mold compound behavior in terms of flowability and warpage aspects, so as to limit process failure. The increased size adaptation (wafer size above Φ300mm or panel larger than 300mm x 300mm) expands the assembly molding challenges even further. Better understanding the flowability fundamentals of mold compound and its impacts on quality and potentially warpage of the wafer/panel for subsequent processes is needed.

Project Purpose

Mold flowability impacts the quality and potentially warpage of the wafer/panel for subsequent processes. Through the study, this project will:
  • Identify key processing factors that impact flowability
  • Establish factors from flowability that impact warpage
  • Identify other material factors that impact post mold warpage
to achieve higher yield in flow and warpage control for mold first WLP/PLP assembly processes.
