Based in Qidong, Nantong, Jiangsu, we focus on the development and manufacturing of Indium Phosphide (InP) substrates and are building a domestic crystal materials supply chain.
Jiangsu Xinguang Yuan Crystal Technology Co., Ltd.(Synlumin) is located in Qidong, Nantong, Jiangsu, the core hinterland of the semiconductor industry in the Yangtze River Delta region. The company focuses on the localization needs of compound semiconductor materials and specializes in the research, development, production, and sales of indium phosphide (InP) substrates and epitaxial materials.
Relying on the industrial resources and technological accumulation of the parent company in the field of semiconductor materials, Xingguang Yuan has been committed to building full process capabilities in crystal growth, wafer processing, and epitaxial processes since its establishment, aiming to solve the industry pain points of long-term dependence on imported high-end InP materials, insufficient delivery time, and service response.
The company's main business covers 2/3/4/6 inch InP single crystal substrates and provides customized and joint development services. The products are widely used in cutting-edge fields such as optical communication, RF devices, infrared detection, and quantum information.
More than 20 years of industry accumulation and process polishing from actual production lines have enabled the core optical element products to reach the industry's advanced level in terms of crystal quality, surface state, and electrical parameter consistency. We adhere to strict process standards and responsive technical services to provide solid guarantees for the efficient operation of our customers' production lines.
Verifiable data defines the boundaries of our capability; a pragmatic approach answers the real needs of customers and the industry.
Grounded in our parent company's firsthand experience in semiconductor materials, we define products and processes by solving real problems, not by stacking technology detached from production.
We follow a fully in-house R&D path, mastering core processes and key parameters in crystal growth and wafer processing to continuously improve material consistency and reliability.
Guided by customer production-line requirements, we provide sample validation, parameter customization and fast-responding technical service, advancing projects together with our customers.
We act on responsibility across environment, social and governance, embedding compliance and sustainability requirements into daily operations.
We integrate environmental factors into production operations and decision-making, applying best practices in pollution prevention, waste reduction and efficient resource use to lower the environmental impact of crystal growth and wafer processing.
We place high priority on employee health and safety, uphold fair employment and reasonable working conditions, and invest in our people's growth through continuous training.
A safety management system with regular training and drills safeguards operations in crystal growth, chemical handling and wafer manufacturing.
Technical training, career development plans and promotion paths support employees' capability growth and long-term development.
We uphold fair employment and respect for worker rights, and require supply chain partners to meet the same standards.
Supplier admission assessments and periodic audits drive continuous improvement in labor practices, ethical sourcing and working conditions.
We are committed to high standards of corporate governance and business ethics, managing compliance, risk and sustainability in a coordinated way at the decision-making level.
We uphold integrity and anti-corruption requirements, with reporting and investigation mechanisms that keep business conduct compliant and transparent.
We comply with the laws, regulations and industry standards of every jurisdiction where we operate, respect and protect intellectual property, and govern technical cooperation.
Tiered management and access control over customer technical data and business information safeguard information and data security.
Quality systems and batch traceability ensure product responsibility is traceable and issues are closed out.
