INTEL FOUNDRY ENGINEERS BLUEPRINT FOR HYPER-LARGE FORM FACTOR AI CHIPS

Summary from the TLDR Hardware newsletter

At the IEEE ECTC conference, Intel Foundry unveiled novel packaging techniques designed to manufacture hyper-large form factor (HLFF) silicon measuring 240mm by 240mm. Addressing the physical limits of single-reticle chips, Intel's design blueprint combines compute die arrays with High-Bandwidth Memory (HBM) using EMIB-T embedded silicon bridges. To maintain reliability across massive package footprints, multi-point underfill material is introduced for dispensing material alongside thick stiffener rings and glass-core substrates that eliminate substrate warping and structural voids during thermal curing.
