Sapphire wafers are single-crystal aluminum oxide (Al2O3) substrates valued for their exceptional hardness, optical transparency, chemical resistance, and thermal stability. Because sapphire is electrically insulating and highly durable, it is widely used in LED manufacturing, GaN epitaxy, RF electronics, silicon-on-sapphire (SOS) technology, MEMS, optical windows, sensors, and semiconductor research. Sapphire substrates are available in several crystal orientations to optimize epitaxial growth and device performance.
Sapphire combines outstanding mechanical, optical, and thermal properties that make it one of the most versatile substrate materials available. Its resistance to heat, scratching, and aggressive chemicals allows sapphire wafers to withstand demanding semiconductor fabrication processes while maintaining excellent surface quality.
Different sapphire wafer orientations are selected based on the intended device and fabrication process.
