TipWhy This Matters

China’s first ‘CIDM’ (collaborative IDM) project — pooling IC-design firms, end-application companies, and the manufacturer as joint investors — founded by Richard Chang (Zhang Rujing), who also founded SMIC. Domestic reporting in 2026 describes Zhang as having since departed the company he founded, citing difficulty retaining talent — a leadership change this tracker has not independently corroborated beyond that single report. By 2026, reported capacity stood at roughly 60,000 wafers/month (8-inch line) and 40,000 wafers/month (12-inch line), with an annual output value around ¥4.6 billion at full capacity. SiEn was added to the US Commerce Department’s Entity List on December 2, 2024, as part of the 140-entity semiconductor package — one of only a handful of wafer fabs directly listed in that round.

Chinese name: 芯恩（青岛）集成电路 (Xīn’ēn (Qīngdǎo) Jíchéng Diànlù)

What does this facility make?

Logic/foundry, analog/power, and RF/wireless chips at 28nm and 40nm on both 200mm and 300mm wafers.

Why does it matter?

A structurally different ownership model (collaborative IDM, not a pure foundry or a single-owner state fab) from every other entry in this tracker, and notable for its founder’s direct SMIC lineage. In September 2026 it opened a separate ‘Industry Innovation Center’ — five R&D buildings on a 30,154 sq m site, explicitly a research/innovation facility rather than a new wafer production line — framed domestically as a shift from ‘scale manufacturing to innovation creation.’
