There is widespread speculation that the United States may inform its own semiconductor manufacturer Intel of confidential data from TSMC, Samsung and other companies to support domestic enterprises. This is related to the current predicament of the semiconductor industry in the United States. According to the American Semiconductor Industry Association (SIA), 75% of the world's semiconductor production capacity is concentrated in East Asia. The global share of semiconductor manufacturing capacity in the United States has declined from 37% in 1990 to 12% today. According to the association's estimates, only 6% of global production centers will be located in the United States in the future. In contrast, mainland China is expected to increase its production capacity by about 40% in the next decade, becoming the world's largest semiconductor manufacturing base. To this end, the United States is trying to transfer more chip production to home. Among them, TSMC is one of the supporters of the localization of semiconductor manufacturing in the United States, but TSMC chairman Liu Deyin also admits that the construction of the factory is "politically driven" because its cost is much higher than TSMC's expectations, and the cost of building a new factory in the United States will be 37% to 50% higher than that in mainland China.
