The semiconductor industry has spent fifty years obsessing over the front end the microscopic etching of transistors onto silicon wafers. But the AI boom has quietly elevated a different discipline to strategic prominence: packaging, the unglamorous back-end process of housing and connecting chips. In 2025, this once-overlooked step has become the industry's most consequential bottleneck and its most fiercely contested prize. The shift is structural, not cyclical. As transistor scaling yields diminishing returns, chip designers are stacking multiple dies logic, memory, and I/O into single packages to achieve performance gains. This makes advanced packaging, particularly TSMC's CoWoS platform, the critical enabler for every major AI accelerator. The consequence: demand has outpaced supply so severely that packaging...
