Foundry chip market shifts from shrinking nodes to packaging as stacking and chiplets become battleground

The semiconductor industry is shifting its technology race from shrinking process nodes to packaging as scaling approaches physical limits. Companies are increasingly relying on 2.5D and 3D stacking and chiplets to meet performance, power and bandwidth demands, driving changes across the value chain that includes IP, libraries and EDA tools. Memory makers SK hynix and Samsung Electronics are advancing their packaging technologies. Intel has also demonstrated GaN-on-silicon chiplet technology and integration with silicon digital control circuits.
