Taiji Industry, a Jiangsu company dating to 1983 and one of the province's earliest listed businesses, supplies the local manufacturing base and workforce, while SK hynix supplies the memory wafers and the process technology, the plant sitting alongside SK hynix's own large fabrication site in Wuxi. It marked its fifteenth anniversary in November 2024.

HITECH Semiconductor (Wuxi) Co., Ltd. files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Hitech Semiconductor (Wuxi) Co., Ltd. (China Daily, Wuxi New District), Hitech Semiconductor celebrates 15th anniversary in WND (Wuxi municipal government) and SK Hynix Semiconductor (China) Co (Wuxi municipal government). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- SK hynix Inc., as of 31 Mar 2026. Value is the equity method carrying amount at 31 March 2026 of KRW 163,062 million, converted at KRW 1,523.5 to USD 1.00, SK hynix's own convenience translation rate in the same prospectus. Classified as a joint venture because the shareholders agreement requires a unanimous vote for relevant activities, so 45% does not give control. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of HITECH Semiconductor (Wuxi) Co., Ltd. where a holder stated one, and are missing where no holder did.
