9. Conclusion (Page 49)

Between 2019 and 2026, China’s semiconductor industry evolved into a global powerhouse in wafer‑fab expansion and mid‑range equipment localization. Domestic firms achieved significant gains in etch, deposition, CMP, cleaning, and packaging tools, driven by massive investments and geopolitical constraints. However, lithography—especially EUV and advanced DUV—remains the defining technological bottleneck. China’s future competitiveness hinges on breakthroughs in optics, lasers, materials, and precision engineering.

The 2019–2026 period represents both extraordinary progress and clear structural limits, shaping China’s semiconductor trajectory for the next decade.
