QANYEGN 99.99% Pure Silicon Metal Elements,14 Semiconductor Monoline Si Block for Industrial and Research Applications(50g)

• ULTRA-HIGH PURITY SEMICONDUCTOR GRADE: 99.99% Pure Silicon Metal Elements meet rigorous ASTM F57 standards for semiconductor manufacturing, ensuring minimal boron/phosphorus contamination (<0.4ppm). Ideal for growing defect-free Czochralski monocrystalline ingots, these Si blocks enable precise doping control in transistor fabrication and MEMS sensor production lines
• THERMALLY RESPONSIVE CONDUCTIVITY: These semiconductor silicon blocks have temperature-dependent resistivity (10-⁴ to 10³ Ω-cm) to optimize the performance of high-power rectifiers and thyristors. Their positive temperature coefficient ensures stable operation of automotive ignition systems and industrial motor drives in environments exceeding 150°C
• PHOTOVOLTAIC EFFICIENCY BOOSTERS: These monocrystalline silicon metal elements can achieve solar energy conversion rates of more than 22.6% in PERC cell production. Pre-doped with a controlled oxygen content (<1ppma), they minimize light-induced degradation (LID) while maintaining structural integrity under the constant UV exposure of desert solar farms
• AVAILABLE FOR PRECISION WAFER PRODUCTION: As a basic ingot material for 300mm wafer fabrication, our 14N purity blocks reduce crystal dislocation density to <500/cm². Laser-marked orientation planes (110±1°) simplify alignment in automated epitaxial deposition systems for 5nm chip foundries
• MULTI-INDUSTRY RESEARCH SOLUTIONS: These semiconductor-grade silicon blocks can be used for advanced applications ranging from quantum computing quantum bit substrates to neutron transmutation doping (NTD) systems. Their ultra-flat surfaces (Ra<0.5μm) meet ISO 4 clean room requirements for lithography mask production and synchrotron detector manufacturing
