Recently, I have been paying attention to investment opportunities in the chip industry chain and found that a relatively complete ecosystem has indeed formed domestically.

From the equipment side, North China Instrument, SMIC, and TuoJing Technology are making good progress in key equipment positioning. Downstream, component suppliers such as Jiangfeng Electronics, NewLaiYingCai, and Fuchuang Precision are supporting the foundation. In the cleanroom sector, Yaxiang Integration, MEA Technology, and Shenghui Integration are also making efforts.

Particularly noteworthy are the several equity partners of Hefei Changxin—HeFei Urban Construction, HeBai Group, and Langdi Group are all involved. Changxin's own industrial chain is also under construction, with Zhaoyi Innovation, Micro Nano, and Jingzhida positioning themselves in core links.

The most challenging part is the photolithography machine. BOLY, Yongxin Optics, and Maolai Optics have made some breakthroughs in optical components. Looking at the entire chain—from upstream equipment, midstream components, to downstream applications—the progress of domestic supply chain supplementation is indeed accelerating.
