Meanwhile, TSMC’s market share in China will be increased to about 50% from 46%.

Though the Taiwan government permitted the establishment of TSMC’s 12-inch fab plant in China. but the government still requires TSMC have to maintain Taiwan’s leading position in the global semiconductor market. Thus, Taiwan government restricts TSMC to keep its most advanced process technology in Taiwan.

According to Taiwan’s regulations, the process technology of TSMC's China fab have to behind its Taiwan fab one generation above. By then, Taiwan gorverment will send officials to view the process technology of TSMC.

In addition, Taiwan government also requires TSMC not to reduce its investment and recruitment scale in Taiwan. Over the next three years, the total amount of investment of TSMC in Taiwan is expected to reach NT$860 billion (NT$300 billion in 2016, NT$280 billion in 2017 and NT$280 million in 2018).
