Various Advanced Packaging Solutions and its Trends

Advanced packaging is developed for high performing computing, that need higher power of computation and memory bandwidth. As the cost per transistor is getting higher and scaling is slowing down, chip partitions are being applied, and advanced packaging is developed to integrate these chiplets homogeneously or heterogeneously. TSMC launched its CoWoS and InFO in earlier 2010s, since then the advanced packaging has been grown up significantly. Intel has its EMIB, Co-EMIB, Foveros and Foveros Omni; comparatively AMD also developed 2.5D, HDCL, FanOut and Cubic package; Samsung’s HBM is a 3D package, they have 2.5D package and closely developed Panel Fan-Out. SPIL has been manufacturing 2.5D, FanOut, FOPoP and FOEB for a while. Similarly, ASE has developed its FoCoS, FOPoP, FOEB, Panel FO and 2.5D. Its FoCoS has been high volume manufactured. Amkor lately publishing the S-connect, and FOHD. PTI and UMTC are immensely developing panel FanOut. Then
JCET has shipped out eWLB (FOSD) for some year, lately certified its FOMCM, and started manufacturing. Similarly to TFME, which is setting up its 2.5D line and its FOPoS has been certified and start manufacturing. In this presentation, various form of advanced packaging with its similarity in term of form factors and challenges are presented. The trends of these advanced packaging are then shared.
