With the explosion of cost and complexity at the most advanced front-end silicon technology nodes, alternatives ways are explored to keep the product manufacturing profitable. Device performances are continuously improved to face the demand for High Performance Computing and Artificial Intelligence.
Advanced Packaging has become a key differentiator for achieving next-generation requirements, and thereby continued sustainability , in the semiconductor industry. Since early 2000, when the Embedded Wafer Level Balling (EWLB) approach was introduced, several flavors of packaging based on fan-out have been presented (INFO, EMIB, SWIFT). With a CARG > 19%, the High-Density wafer level Fan-Out is the most promising market, with more and more players moving away their packaging from wire bonding .
Despite the maturity of the advance packaging industry, we are still in an era where several issues can put at risk the process chain. Therefore, the need of process control solutions with systems as much as possible capable of covering inspection and metrology needs at 360 degree on the very same platform. Key process steps like molding and passivation in WLFO or TSV etch in 3D stacking are still requiring major control. RDL entering the sub-micron territory also represents a challenge in term of metrology & inspection.
In this paper, we are presenting our progress in developing solutions for the Advanced packaging arena by combining inspection and metrology strategies to identify the root cause of the yield loss. Multiple inspection techniques are used to identify and classify visible and invisible defects at each surface of the wafer. Complementary metrology techniques are used to secure the process development and high volume manufacturing. Customizing the solution is the new way to secure the manufacturing.
