Estimated investment for the project ranges from NT$500 billion to NT$600 billion.
This capital expenditure equals approximately US$15.8 billion to US$18.9 billion.
TSMC shares rose 6.6% in Taiwan trading following the news.
The company has not officially confirmed the specific plan but continues to coordinate with authorities for domestic expansion.
