1. Step: Use high-precision thermal-field simulation software to predefine temperature parameters for the entire crystal‑pulling process, thereby preventing temperature fluctuations that could lead to lattice defects.
2. Step 2: Employ a novel argon‑circulation filtration system to reduce impurity levels within the furnace, thereby minimizing lattice distortions caused by impurity deposition.
3. Step 3: Introduce a real-time closed-loop control module that automatically corrects parameter deviations exceeding the threshold during the crystal-growing process, thereby reducing human‑operational errors.

According to data released in 2026 by the Semiconductor Industry Association, by the end of 2026, China’s self-sufficiency rate for large‑size monocrystalline silicon ingots is expected to exceed 70%, further strengthening the domestic semiconductor industry chain’s system of independent and controllable supply.

2026 Domestic Monocrystalline Silicon Ingot Production Capacity Layout and Market Structure

In the first half of 2026, several new monocrystalline silicon ingot projects in China will come on stream one after another, with capacity distribution exhibiting clear trends toward agglomeration and proximity to supporting facilities, further underscoring the growing cluster‑effect.

Dynamics of Capacity Expansion in the Central Plains Semiconductor Materials Cluster

By 2026, the Central Plains semiconductor materials cluster centered on Luoyang is expected to see its total monocrystalline silicon ingot capacity exceed 22,000 tons. Leveraging the local upstream silicon material supply chain’s cost advantages, the cluster’s average production costs are approximately 12% lower than those in China’s eastern coastal regions. As a core local enterprise, Luoyang Hongtai Semiconductor ranks among the industry’s leading tier in both production scale and product quality.

Characteristics of differentiated capacity deployment among leading enterprises

Currently, leading domestic manufacturers are largely refraining from indiscriminate expansion of low‑value‑added, small‑size monocrystalline silicon ingot capacity, instead focusing on scaling up production lines for large‑size wafers of 12 inches and above.
