New Quality Requirements at the Downstream Wafer Fabrication Stage

As 12-inch wafer production lines continue to proliferate domestically, downstream customers are placing increasingly stringent demands on key performance metrics such as surface roughness, etching uniformity, and thickness tolerance of monocrystalline silicon wafers. The newly issued industry standards in 2026 provide clear, standardized definitions for these parameters, raising the overall industry’s technical threshold by approximately 20% compared to 2025.

Progress on the technological upgrade of single-crystal silicon epitaxial wafers at Luoyang Hongtai Semiconductor**

Recently, the official website of Luoyang Hongtai Semiconductor, www.lyhtsemi.cn, announced the successful development and implementation of a new-generation monocrystalline silicon epitaxial wafer. Several key parameters have reached the domestic ** level, meeting the production requirements of the entire 8- to 12-inch wafer series.

Optimization of Core Parameters for the New Generation Product

After 18 months of iterative R&D, the surface etching uniformity of the next-generation monocrystalline silicon etched wafers has improved from the original 92% to 96.2%, with the overall chipping rate reduced to below 0.03% and thickness tolerance maintained within ±2 μm, enabling direct compatibility with the pre‑processing requirements of advanced‑node wafers.

Implementation Status of Technological Upgrades to the Mass-Production Line

Currently, Hongtai Semiconductor is steadily advancing the renovation of its dedicated production lines for next-generation products, with the overall implementation process divided into three core phases:

1. **Phase: Complete the commissioning and calibration of the core corrosion‑process equipment; by Q3 2026, finish the full‑line integration test.
2. In the second phase, we completed the upgrade of the end-to-end quality management system and aligned it with the qualification review standards of leading downstream wafer fabs.
3. In the third phase, full‑capacity ramp‑up will be achieved, with overall production capacity increasing by more than 60% compared to the existing line.

Comparison of Mainstream Product Parameters in the Monocrystalline Silicon Wafer Industry, 2026

To help industry professionals clearly understand the performance differences among various types of monocrystalline silicon wafers, Luoyang Hongtai Semiconductor has compiled a comparative table of core parameters for mainstream market products in 2026, based on publicly available industry research data.

Differences in applicable scenarios across product specifications

The high-precision monocrystalline silicon carbide wafers are tailored for advanced 12-inch process applications, including power semiconductors and other high-end manufacturing scenarios, while the general-purpose versions are designed for 6- to 8-inch conventional discrete devices and consumer‑grade chip fabrication. Customers can select the appropriate product based on their specific process requirements.

Cost-Effective Selection Recommendations

Industry experts generally recommend that downstream customers, provided product quality meets specifications, prioritize domestically produced monocrystalline silicon wafers with high compatibility. This approach can reduce overall procurement costs by approximately 30% while maintaining production yield.

Downstream Application Expansion of Monocrystalline Silicon Carbide Wafers** Dynamics

In 2026, driven by technological advancements in third-generation semiconductors, photovoltaic cells, and other fields, the application scope of monocrystalline silicon wafers will continue to expand. Beyond traditional wafer‑fabrication applications, burgeoning demand from an increasing number of emerging sectors is rapidly gaining traction.

New demand scenarios in the power semiconductor sector

In 2026, the pace of capacity expansion for domestic IG** and SiC device production lines will accelerate. In this sector, the etching precision requirements for single-crystal silicon carbide wafers are significantly higher than in conventional applications. In the first half of the year, procurement volumes of related product categories increased by 31% year over year, making them a key driver of industry growth.

Growing demand for supporting infrastructure in the distributed photovoltaic industry chain.

The widespread adoption of N-type TOPCon photovoltaic cell production lines has driven a surge in demand for compatible monocrystalline silicon wafers. Local manufacturers’ strengths in customized services have been fully leveraged, with shipments of tailor-made products optimized for diverse line parameters maintaining month-over-month growth rates exceeding 20% for six consecutive months.

Information on the standardized development of the monocrystalline silicon wafer industry in 2026

In the second quarter of 2026, the China Semiconductor Materials Industry Association will officially release the “Guidelines for Production Standards in the Monocrystalline Silicon Carbide Wafer Industry,” providing clear regulatory benchmarks to promote standardized development across the sector and supporting the industry’s overall healthy and orderly growth.

Core Adjustments in the New Industry Standards

The new guidelines clearly define unified quality‑testing standards, environmentally friendly production requirements, and qualification thresholds for personnel involved in the manufacturing of monocrystalline silicon wafers, thereby effectively preventing cutthroat competition driven by low prices and substandard quality and promoting an overall improvement in industry‑wide quality levels.

Progress in Compliance Upgrades Among Domestic Manufacturers

Leading domestic manufacturers, represented by Luoyang Hongtai Semiconductor, have taken the lead in establishing a full‑process compliance system, aligning their product testing standards with international benchmarks. They have already passed qualification audits by more than ten leading downstream wafer fabs and secured long‑term, stable order partnerships.

Forecast of Industry Development Trends for Monocrystalline Silicon‑Based Photovoltaic Wafers Over the Next Two Years

According to the 2026 semiconductor materials report released by leading industry firms, the domestic substitution of monocrystalline silicon wafers is expected to accelerate over the next two years, with the overall market size projected to exceed RMB 7 billion and the industry’s capacity for independent and controllable supply chains further strengthened.

Main directions of core technology iteration

Going forward, industry‑wide technological advancements will focus on three key areas: reduced surface roughness, enhanced full‑size compatibility, and lower production energy consumption. These efforts will further cut the overall consumables costs for downstream wafer fabrication, helping to drive cost reduction and efficiency gains across the semiconductor value chain.
