TSMC's $40 billion Arizona fabrication plant, a cornerstone of the US CHIPS Act, is facing severe challenges in replicating its successful Taiwanese manufacturing model, highlighting the complexities of onshoring advanced technology.
Major hurdles include a nascent local supply chain, forcing the import of basic materials like sulfuric acid from Taiwan, and a shortage of skilled labor, which has contributed to significant construction delays and cost overruns.
The project's costs are estimated to be 50-100% higher than in Taiwan, leading to production being delayed from 2024 to 2025 and causing key suppliers to pause their own US expansion plans.
Despite these struggles, the venture is catalyzing a new semiconductor ecosystem in Arizona, but TSMC has indicated its most advanced chip technologies will remain in Taiwan, raising questions about the strategic goals of the onshoring effort.
