Presenting the Best Semiconductor Materials in All Three Generations

Here at Alsil Materials, we provide you with the highest quality semiconductor materials covering all three generations, including silicon substrates, gallium arsenide, sapphire, and silicon carbide. All our silicon wafers are manufactured to SEMI standards. We also take into account the specifications of our customers during the manufacturing process and guarantee the precision of the highest industry standards.

Our services also extend to silicon wafer coating as well as coring for non-standard orientations and diameters. We offer the highest quality and ultra-pure silicon through the FZ growing process.
