Samsung Electronics plans to produce HBM5 using chips fabricated on its internally developed 2nm process, targeting mass production around 2028. HPB will be the primary in-package thermal-management technology; HPB is a metal thermal-conduction structure, typically copper-based, integrated into the package and offering roughly 500–1,000x higher thermal conductivity than polymer materials such as substrate, DAF or EMC.
