Preferred Supplier of High-Quality 6/8/12-Inch Recycled Wafers and Dummy Wafers

Silicon wafers serve as the core substrate material for semiconductor chip manufacturing, available in diameters of 6 inches, 8 inches, and 12 inches. Dummy wafers are specifically used to fill equipment during the wafer manufacturing process and are essential auxiliary consumables for production management in wafer fabs. Together, they ensure the stable operation of the entire process, from chip R&D and equipment debugging to mass production.

GXSC operates precision processing and supply lines for recycled silicon wafers and dummy wafers. Relying on a comprehensive nine-step standardized process—from raw material verification, film stripping and parameter testing, mirror polishing, and multi-stage deep cleaning, to final comprehensive testing, cleanroom packaging, temperature-controlled storage, and precise shipping—we achieve closed-loop control throughout the entire process.

Through professional polishing and restoration, particle-level cleaning, and multi-dimensional parameter testing, GXSC’s recycled wafers can meet customers’ customized requirements for electrical performance, surface flatness, and cleanliness, while offering a competitive cost advantage.
