- FZ Silicon Rod
Float-Zone Single Crystal Silicon (FZ-Si) is renowned for its exceptional high-purity silicon and low oxygen content, achieved through the advanced Float-Zone process. This method eliminates impurities by zone refining, resulting in near-intrinsic semiconductor properties with minimal defects and crystal lattice perfection. Due to its ultra-pure characteristics, FZ-Si is critical in semiconductor applications, especially in power electronics and high-frequency devices requiring precise electrical performance. Additionally, its superior optical transparency and structural integrity make it ideal for optical applications, such as infrared lenses, laser components, and advanced photovoltaic devices. As a cornerstone of modern technology, FZ-Si bridges innovation in both electronics and photonics industries.

Technical Advantages

  1. Poly silicon ingots can be used forprocessing large-sized silicon components and silicon target materials.The purity of silicon ingots produced by Jingge Semi can reach 6N,which is a key basic material for manufacturing semiconductor devices.

  2. Poly silicon ingots can be processed in to large-sized silicon rings for etching purposes,as well as silicon wafers and tubes for sputtering coating purposes.

  3. Jingge Semi full melt and semi-melt processes enable unmatched columnar grain uniformity, minimizing defects and maximizing structural integrity for high-stress applications.

  4. Advanced refining techniques ensure ultra-low oxygen and impurity levels (<1ppb), critical for semiconductor silicon rings requiring extreme electrical stability.

  5. Switch seamlessly between full melt (ultra-dense ingots) and semi-melt (cost-optimized batches) modes to meet diverse industry demands.

  6. On demands from client,Jingge Semi can make ingot in different shapes and sizes(up to 1200mm diameter).
