- Lucas: So Taiwan Semiconductor is already the world's most important company — we've done episodes on that. But there's a specific bottleneck within the chip supply chain that's actually becoming the new choke point, and it's not the lithography or the EUV machines. It's packaging. Luna: Packaging — you mean the plastic or ceramic case around the chip? I thought that was the commoditised part. Lucas: That's the old view. Advanced packaging — especially something called CoWoS, which stands for Chip-on-Wafer-on-Substrate — is now the critical enabler for AI accelerators like NVIDIA's H200 and next-gen Blackwell chips. Taiwan Semiconductor essentially dominates this market, with something like 90 percent share in the most advanced forms. Luna: I knew they led in leading-edge manufacturing, but 90 percent in packaging too? That's a staggering concentration. Lucas: It is. And it's becoming a strategic vulnerability for everyone else. CoWoS is how you stack high-bandwidth memory directly next to the compute chip, reducing latency and power consumption. Without it, the AI models we keep talking about — GPT-6, Google's Gemini 3 — would be far more expensive to run. The packaging is the hidden tax. Luna: And the geopolitics? If tensions escalate, Taiwan Semiconductor could theoretically throttle not just chip fabrication but also the packaging step, right? Lucas: Exactly. Even if you fab a chip elsewhere — say at Samsung or Intel — you still might need to send it to Taiwan for advanced packaging. That's a single point of failure. The US, Japan, and Europe are now racing to build their own advanced packaging capacity, but it takes years. The US CHIPS Act allocated about $3 billion specifically for packaging R&D, but actual fabs won't be online until 2028 at the earliest. Luna: So for now, Taiwan holds the keys. And speaking of Taiwan, the EWY ETF, which tracks South Korean stocks, is up 3.6 percent in the last five days. That's partly because South Korea's memory makers — Samsung and SK Hynix — are the main suppliers of the high-bandwidth memory that goes into these CoWoS packages. So they benefit from the same AI demand. Lucas: Right. It's an ecosystem. Taiwan does the packaging, Korea provides the memory, and NVIDIA designs the chip. But the bottleneck remains the packaging capacity. Taiwan Semiconductor has been expanding CoWoS capacity like crazy — they doubled it last year and plan to double it again — but demand from hyperscalers is growing even faster. Some analysts estimate a 20 percent supply-demand gap through 2027. Luna: That gap has real pricing power. If you're a startup trying to get AI chips made, you're not just waiting for fab capacity at TSMC — you're also waiting for packaging capacity. And TSMC can charge a premium for that. Lucas: Yeah. And it's not just CoWoS. There's also something called 3D stacking — stacking logic chips directly on top of each other — which TSMC calls SoIC, or System-on-Integrated-Chips. That's even more cutting edge. Apple is already using it for some of their future chips. So the packaging race isn't just about today's bottleneck — it's about who controls the next generation of integration. Luna: This reminds me of something — our conversations on this show often help us see these hidden layers in global trade. And I know we normally don't do this, but if these episodes have helped you think about your work or investments a bit differently, there's a way to support the show that keeps it ad-free and independent. Lucas: Yeah, it's at buy me a coffee dot com slash fexingo. Just a small gesture from listeners who find value in what we do — it helps us keep digging into these angles without sponsors calling the shots. Luna: And we really appreciate it. Back to packaging — do you think Intel's push into advanced packaging could actually challenge TSMC in the next few years? Lucas: Intel has their own technology called Foveros, and they're building a massive packaging facility in New Mexico. But they're years behind in volume and yield. TSMC's advantage isn't just the technology — it's the manufacturing scale and the co-development with customers. NVIDIA and AMD have been working with TSMC on packaging for years. You don't replicate that trust quickly. Luna: So the packaging bottleneck reinforces something we've seen across this series: that global trade in tech is becoming more regionalised, but also more concentrated in a few critical nodes. Taiwan is one of those nodes. Lucas: Exactly. And as long as AI demand drives the semiconductor cycle, Taiwan's leverage only grows. We should keep an eye on the FXI, the China ETF — it's down almost 5 percent in a week. That partly reflects concerns about China's own chip ambitions and the decoupling pressure. If China can't access advanced packaging from TSMC due to export controls, their AI progress hits a wall. Luna: Which is ironic — because China is trying to build its own semiconductor ecosystem, but packaging is one of those areas where the gap is widest. They have some domestic players like JCET, but they're not at TSMC's level for the advanced stuff. Lucas: Right. And the trade data backs up the trend: US imports of goods and services are running at $4.4 trillion annualised, with a deficit of about $55 billion in April. A big chunk of that deficit is semiconductor-related flows — chips and packaging equipment going back and forth across the Pacific. So the packaging story isn't just tech — it's trade policy. Luna: And the dollar is strong again — the trade-weighted index is at 120.4. That makes it more expensive for foreign buyers to invest in us based packaging R&D, which actually slows the reshoring effort. Lucas: Yeah. The strong dollar is a double-edged sword for the CHIPS Act. On one hand, it makes imported equipment cheaper for US fabs. On the other, it makes US exports of chipmaking services less competitive. Packaging is a global business — the equipment is made by companies in the Netherlands and Japan — so the FX dynamics matter. Luna: So to sum up the packaging bottleneck: TSMC owns it, AI needs it, competitors are years behind, and geopolitics makes it more precarious by the day. Lucas: That's the picture. And as we watch the Magnificent 7 stocks pull back — like Alphabet had its worst day in over a year yesterday — the underlying hardware demand hasn't changed. AI capital expenditure is still surging. The bottleneck just means that spending flows to a narrower set of suppliers, and Taiwan Semiconductor is at the very top of that list. Luna: Thanks for joining us on International Business with Fexingo. We'll be back tomorrow with another angle.
