A sapphire wafer is a thin, circular substrate created by crystallizing high-purity single-crystal sapphire artificially and then slicing it into thin pieces.
Utilizing the exceptional hardness, strength, thermal conductivity, optical transparency, and chemical stability of sapphire, these wafers are employed in a variety of sectors including semiconductor manufacturing, optical devices, medical and biotechnological applications, precision instruments, and even jewelry.
Their use is driven by features such as compatibility with high temperatures and frequencies, unique optical properties, biocompatibility, and remarkable hardness and strength. These characteristics make sapphire wafers ideal substrates for advanced semiconductors, optical devices, medical equipment, and precision instruments. Their production involves crystal growth, slicing, polishing, cleaning, and meticulous inspection processes, ensuring the highest quality. Key attributes of sapphire wafers encompass high hardness, strength, thermal conductivity, optical transparency, chemical stability, biocompatibility, and excellent insulation resistance.
