July 1 — Youyan Silicon began construction of a large-diameter semiconductor monocrystalline silicon project in Baotou Rare Earth High‑Tech Zone, Inner Mongolia. The site will include about 50,000 sq m of single‑crystal production facilities; at full capacity it is expected to supply more than 1,000 tonnes/year of monocrystalline silicon for integrated circuits and for etching equipment, materially boosting the company’s wafer and semiconductor components output and supply security.
