TSMC, Intel, and Corning Are Betting on Glass — The End of the Silicon Interposer

Everyone watches the transistor. But the real limit on today's AI chips isn't the transistor — it's the package: the silicon interposer that wires the processor to its memory. It's hitting a physical wall, and the way past it is glass. This is the shift from CoWoS to glass substrates and panel-level packaging (CoPoS): why silicon interposers are running out of room on size, shape, and warpage, what glass fixes, how panel-level packaging flips the economics, and who actually wins if the package turns to glass. ▶ Playlist — The AI Compute Crunch:    • The AI Compute Crunch — Can the Hardware K...   Chapters 0:00 The real bottleneck isn't the transistor 0:45 What an AI accelerator really is 1:42 The silicon interposer wall 3:01 What glass brings 4:10 Panel-level packaging — CoPoS 5:26 Who actually wins (the supply chain) 6:41 The verdict 8:02 Closing No hype, no hot takes — just how the chips really get built.
