Semiconductor packaging evolves to 3.5D to overcome scaling limits

By PulseAugur Editorial · [1 sources] ·

The semiconductor industry is exploring advancements in 2.5D and 3.5D packaging to overcome the scaling limitations of current interposers and substrates. This evolution aims to achieve tighter D2D pitch, increased bandwidth density, and reduced energy consumption per bit, addressing reticle constraints. As integration complexity grows with more HBM stacks, chiplets, and bonding interfaces, maintaining high yield becomes paramount, necessitating stringent process control and advanced inspection techniques. AI

IMPACT Advancements in semiconductor packaging could enable more powerful and efficient AI hardware by increasing chip integration density and bandwidth.
