Addressing the PVD challenges in High Density FO-WLP
Fan-Out Wafer Level Packaging (FO-WLP) is an established advanced packaging format within mobile and automotive sectors, enabling smaller, reliable packages with better performance in a cost-efficient manner. Now starting to expand into applications such as High Performance Computing (HPC) and Networking which require a higher level of integration with greater I/O density, High Density FO-WLP is competing against relatively expensive 2.5D interposer solutions.
In June 2020, Yole projected Fan-Out revenues to grow from $1,256M in 2019 to an estimated $3,046M by 2025, with the largest growth within the sector being in High Density applications[1].
In High Density Fan-Out (HD FO), increased I/O density requires tighter line/space patterning for the redistribution layers (RDL). PVD is used to deposit Cu seed metal prior to RDL electroplating. With an abundance of organic material on the wafer, managing contamination to maintain PVD metal electrical quality and low contact resistance (Rc) is critical, more so as I/O density is increased, and contact structures reduce in size.
Learn how FO-WLP is evolving and why SPTS is the leading PVD production supplier to this important market. We will explain how SPTS’s Sigma® fxP PVD system has all the necessary features that high volume manufacturers require for these emerging HD FO applications, such as specialized pre-treatment technology designed to manage contamination, maintain low and stable Rc, while delivering high uptime, throughput and yields.
