Interposer technology allows multiple dies to be placed on a single substrate and operate as one processor. Samsung has announced its latest 2.5D package featuring a silicon interposer around 100㎛ thick, which has four HBMs and one logic die. The new I-Cube4 is aimed at HPC, AI, 5G, and large-scale data center solutions.
