CoPos (Chip-on-Panel-on-Substrate) Wiki - SemiWiki Instead of building redistribution and interposer structures on round wafers, CoPoS forms them on large rectangular panels, then mounts the finished module onto an organic or glass package substrate
TSMC Prepares CoPoS: Next-Gen 310 × 310 mm Packages In response to the need for more space, TSMC has unveiled plans for CoPoS, or "Chips on Panel on Substrate," which could expand substrate dimensions to 310 × 310 mm and beyond By shifting from round wafers to rectangular panels, CoPoS offers more than five times the usable area
CoWoS vs. CoPoS vs. CoWoP: TSMC Advanced Packaging Explained CoPoS solves the size and warpage issues of ultra-large chips through panelization, while CoWoP optimizes packaging costs by replacing IC substrates with high-performance PCBs – both technologies complement CoWoS to meet diverse market demands
Glass vs CoWoP vs CoWoS vs CoPoS: Key Differences Explained The CoPoS and CoWoP technologies are geared towards cost-effective scaling, based on a panel-level process or a direct wafer-to-PCB connection While CoPoS lowers cost by using large panels, CoWoP enhances flexibility for different layouts
