The Quiet Revolution in Chip Packaging Technology

25 May 2026 · 11 min · S1 E10

For decades, we've focused on shrinking transistors to make chips faster. But as Moore's Law slows, a different revolution is happening in chip packaging — how chips are physically assembled and connected. In this episode, Lucas and Luna explore the 40-year history of chip packaging, from wire bonding to today's 3D stacking and hybrid bonding. They zero in on a specific breakthrough: TSMC's 3D SoIC technology, which stacks logic chips directly on top of each other, reducing signal delay and power consumption by 40% compared to traditional 2D chips. They discuss why AMD's use of chiplet packaging in its Ryzen and EPYC processors gave it a 2-year lead over Intel, and how Apple's M1 Ultra used TSMC's InFO packaging to connect two dies as if they were one. The hosts also touch on the economics: advanced packaging now accounts for 20% of semiconductor capital spending, up from 5% a decade ago. This episode shows that the next leap in computing performance won't come from smaller transistors, but from smarter ways to put them together.
