TSMC Arizona to Begin 4nm Production in H2 2025, 30% Higher Costs
TSMC's Arizona facility is reportedly on track to begin mass production of 4nm chips in the second half of 2025, with major tech companies like Apple, NVIDIA, AMD, and Qualcomm expected to be among its primary customers. However, production costs are projected to be significantly higher than in Taiwan. This marks a major milestone in TSMC's US expansion, following the passage of the CHIPS Act and the construction of one of the largest foreign chip fabrication plants. According to a report by Yonhap, the Arizona facility's Phase 1 (1A) plant will start producing 4nm wafers, initially outputting around 20,000 units per month. Phase 2 will see a move to 2nm production in 2028, although this remains uncertain due to "technology transfer" disputes. Higher Production Costs in Arizona One significant aspect of TSMC's Arizona operations is the higher production costs. The report claims that manufacturing in Arizona will be about 30% more expensive than in Taiwan. This…
