Intel seizes opportunity as TSMC faces AI chip packaging constraints

The AI chip supply chain has a bottleneck, and it’s not where most people expect. It’s not in the fabs where transistors get etched onto silicon wafers. It’s in the back end of the process, where those chips get packaged into the complex multi-die modules that power AI workloads. TSMC, the world’s dominant chipmaker, has its advanced packaging lines fully booked through 2027. The packaging problem, explained TSMC’s packaging technology, called CoWoS (Chip-on-Wafer-on-Substrate), has become the gold standard. Nvidia’s GPUs use it. AMD’s MI300 uses it. The demand has far outstripped supply. TSMC’s CEO acknowledged during the company’s July 2026 earnings call that packaging capacity limitations are actively constraining customer growth. Intel’s EMIB play Intel’s EMIB technology, or Embedded Multi-die Interconnect Bridge, uses small silicon bridges embedded in the package substrate to connect chiplets, rather than requiring an expensive silicon interposer like CoWoS does. Intel has been positioning EMIB and its companion 3D stacking technology, Foveros, as the cornerstone of its foundry comeback story. Google has committed to ordering more than 3 million units of Intel’s EMIB-T packagi...
