High Purity Al2O3＞99.995% R9 Mirror Polished EPI-Ready Wafer edge R-type
JDCD08-001-001 Diameter 50mm Sapphire substrate wafer , Thk 430μm, crystal orientation C/M0.2, OF length (mm) 16 LED chip,substrate material
High performance of Silicon (Si) and Germanium (Ge)-based devices can be made possible through Sapphire Substrate, which allows chipsets to be very fast in performance. The presence of Si and Ge ensures high electron mobility and low twin defect density in the chipsets. Electron mobility in the SiGe devices is higher than in the case of Si devices.
