Semiconductors and Photovoltaics Drive Quartz Industry Growth; High-Purity Quartz Products Enter Expansion Window

In the semiconductor field, core processes such as wafer manufacturing, etching, diffusion, and thin film deposition highly rely on precision quartz components such as quartz boats, quartz furnace tubes, quartz rings, quartz bell jars, and vacuum quartz cavities. With the continuous expansion of mature domestic processes, steady breakthroughs in advanced processes, and the increasing demand for self-control in the wafer fab supply chain, the market demand for high-purity quartz consumables in the semiconductor industry maintains steady growth. Quartz products for semiconductors have extremely stringent requirements for raw material purity, processing precision, surface cleanliness, thermal shock resistance, and airtightness. In the past, high-end products were long monopolized by overseas companies. In recent years, domestic quartz companies have made continuous breakthroughs in core processes such as high-purity raw material purification, ultra-precision machining, precision quartz welding, and low-stress forming. This has significantly improved product yield, stability, and consistency, leading to mass production and integration into the supply chains of leading domestic wafer fabs, and continuously opening up opportunities for high-end domestic substitution.

The photovoltaic industry has become the core second growth driver for the quartz industry. With the comprehensive replacement of traditional P-type cells by new-generation high-efficiency battery technologies such as N-type TOPCon and HJT, the frequency and wear of quartz carriers, quartz tubes, and quartz boats in key photovoltaic processes such as high-temperature diffusion, coating, and etching have significantly increased. The mass production of N-type cells places higher demands on the cleanliness of the production environment, the stability of components, and high-temperature resistance, directly driving the iterative upgrading of demand for high-end photovoltaic-specific quartz products. Against the backdrop of sustained high global photovoltaic (PV) installations and continuous expansion across the industry chain, PV quartz consumables are characterized by high demand, concentrated delivery, and rapid iteration, providing a stable and sustainable incremental market for domestic quartz manufacturers. This, in turn, is forcing the industry to accelerate automation, standardization, and large-scale production upgrades.

Besides the core semiconductor and PV markets, demand continues to expand in high-end laser equipment, precision optical instruments, new energy equipment, and aerospace exploration, further broadening the application boundaries of quartz materials and forming a multi-faceted industry development pattern. However, the industry still faces significant structural shortcomings: limited supply of ultra-high purity quartz raw materials, high difficulty in processing high-end irregular-shaped precision parts, numerous downstream customized products, and difficulties in controlling the precision of mass production remain core bottlenecks hindering domestic companies from entering the high-end market. In this context, leading manufacturers with integrated raw material processing, ultra-precision irregular-shaped processing, precision welding, and stable mass delivery capabilities continue to demonstrate their competitive advantages.

Industry analysts indicate that the semiconductor industry's cyclical recovery, coupled with the continued increase in the penetration rate of new PV technologies, has officially ushered in a high-growth phase driven by both semiconductors and PV. The industry's growth logic has shifted from low-end, large-scale expansion to a comprehensive focus on high-end, precision, customization, and domestic production. Downstream end-user companies, driven by both supply chain security and cost reduction/efficiency improvement considerations, will continue to increase their support and investment in high-quality domestic quartz suppliers. Domestic companies with solid technical capabilities, stable quality, and efficient delivery will continue to capture import substitution market share.

In the long run, as domestic quartz purification, precision forming, and special welding processes continue to mature, domestically produced high-purity quartz products will deeply penetrate advanced semiconductor processes and the high-end N-type photovoltaic industry chain, continuously addressing the shortcomings in upstream basic materials, strengthening the resilience of the domestic high-end equipment and new energy industry chain supply chain, and continuously promoting the high-quality and independent development of my country's new materials and advanced manufacturing industries.
