In the rapidly evolving landscape of microelectronics, the Quartz Plate for Semiconductor Wafer Fabrication has emerged as an indispensable consumable. As semiconductor nodes shrink to 5nm, 3nm, and beyond, the tolerance for contamination and thermal instability approaches absolute zero. High-purity fused silica quartz plates act as the foundational substrate and protective barrier in various wafer processing environments, offering unmatched thermal shock resistance, exceptional optical transmission, and chemical inertness.
The global commercial status of semiconductor-grade quartz is experiencing unprecedented growth. Driven by the surge in AI computing, 5G infrastructure, and IoT devices, wafer fabs worldwide are operating at maximum capacity. This surge translates directly into a massive demand for ultra-pure quartz components. Unlike standard industrial glass, semiconductor quartz plates must possess a purity level exceeding 99.999% (5N), ensuring that alkali metal impurities (like Sodium, Potassium, and Lithium) are kept to parts-per-billion (ppb) levels to prevent fatal wafer contamination during high-temperature cycles.
Our quartz plates exhibit a near-zero Coefficient of Thermal Expansion (CTE), allowing them to withstand rapid thermal processing (RTP) where temperatures spike to 1200℃ in seconds. Their superior dielectric strength also makes them the premier choice for insulating components in plasma-enhanced chemical vapor deposition (PECVD) and dry etching chambers, safeguarding delicate silicon wafers from plasma damage.
Lianyungang Southeast Quartz Products Co., Ltd., established in 2015, is located in Donghai County, Lianyungang City, Jiangsu Province—a national base for silicon material industry. As a professional manufacturer integrating R&D, design, production, sales and import & export trade, the company relies on the superior high-quality quartz ore resources in Donghai County, deeply engages in the deep processing of quartz glass, and has become a core supplier of quartz consumables for photovoltaic, semiconductor, laboratory, chemical, lighting and other industries with mature production technology, strict quality control system and complete customized services.
The company has standardized production workshops, advanced quartz processing equipment and a professional R&D team, with full-process production capacity from quartz raw material processing to finished product manufacturing. It can produce a full range of quartz products, including high-purity fused quartz tubes, quartz furnace tubes, quartz bell jars, quartz boats, quartz lamp holders, quartz crucibles, quartz instruments, and tri-acid purification equipment. All products are made of high-purity fused quartz raw materials, featuring excellent high-temperature resistance (up to 1200℃), thermal shock resistance, corrosion resistance, high light transmittance and good electrical insulation performance, which can meet the demanding working conditions such as vacuum environment, high-temperature sintering, atmosphere control and precision experiments in modern wafer fabs.
The integration of quartz plates in semiconductor manufacturing spans across multiple critical stages. From initial wafer cleaning to complex nanometer-scale lithography, the structural integrity of quartz guarantees yield rates and device reliability.
In dry etching processes, quartz plates serve as dielectric windows and focus rings. They must withstand highly corrosive fluorinated plasmas. High-purity quartz minimizes particle generation, preventing micro-masking defects on the wafer surface. In Chemical Vapor Deposition (CVD), quartz plates provide an inert, heat-resistant platform for uniform film deposition.
During thermal oxidation and dopant diffusion, silicon wafers are subjected to extreme temperatures. Quartz plates, boats, and furnace tubes maintain their geometric stability without sagging or warping. Their resistance to heavy metal diffusion ensures that the intrinsic properties of the silicon substrate remain uncompromised.
Wafer cleaning uses aggressive chemicals like RCA cleans (SPM, APM, HPM) and hydrofluoric acid. Custom quartz plates and digestion tubes offer unparalleled chemical resistance against strong acids and bases (excluding HF), providing a pristine environment for removing organic, inorganic, and metallic contaminants from the wafer.
Equipped with advanced CNC machining centers, high-temperature annealing furnaces, and Class 100 cleanroom packaging facilities, our factory is designed to meet the rigorous standards of the global semiconductor supply chain.
Adhering to the philosophy of "Quality First, Customer Supreme, Innovation-Driven, Integrity Management", the company has established a complete quality inspection system. All products undergo multiple tests such as helium mass spectrometry leak detection, pressure resistance test and purity test before leaving the factory to ensure stable performance, no impurities and no leakage. Meanwhile, the company provides flexible customized services, and can customize product sizes, structures and specifications according to customers' equipment parameters and process requirements, quickly responding to personalized orders.
With reliable product quality, efficient delivery capacity and thoughtful after-sales service, the products of Lianyungang Southeast Quartz Products Co., Ltd. not only cover all provinces and cities in China, but also are exported to many countries and regions in Europe, America, Southeast Asia, the Middle East, etc., winning wide recognition and trust from customers at home and abroad. In the future, the company will continue to deeply cultivate the field of quartz products, continuously improve technological innovation and production technology levels, and strive to provide global customers with higher-quality and more professional quartz product solutions, contributing to the high-quality development of high-end manufacturing and scientific research fields.
As the semiconductor industry pushes towards the angstrom era (such as 2nm and 1.8nm nodes) and embraces complex 3D packaging (like GAA transistors and 3D NAND), the specifications for quartz plates are becoming exponentially stricter. The future demands quartz with ultra-low hydroxyl (OH) content to prevent deep UV absorption in advanced lithography systems. Furthermore, the integration of AI in manufacturing requires tighter dimensional tolerances, pushing quartz machining from micrometers to nanometer-level precision.
We are actively researching surface modification technologies for quartz plates to enhance their lifespan in highly aggressive fluorocarbon plasma environments. By reducing the erosion rate of quartz components, fabs can significantly decrease machine downtime and lower the Total Cost of Ownership (TCOO). Our commitment to R&D ensures that our quartz solutions will remain at the forefront of semiconductor wafer fabrication technologies.
From raw material selection to final precision polishing, our rigorous production process guarantees the highest purity and dimensional accuracy required for semiconductor wafer fabrication.
