PAM-XIAMEN provides both single crystal and polycrystalline GaAs wafer ( Gallium Arsenide ) for opto-electronics and micro-electronics industry for making LD , LED , microwave circuit and solar cell applications , the wafers is in diameter range from 2" to 6" in various thicknesses and orientations. We offer single crystal GaAs wafer produced by two main growth techniques LEC and VGF method , allowing us to provide customers the widest choice of GaAs material with high uniformity of electrical properties and excellent surface quality . Gallium Arsenide can be supplied as ingots and polished wafer, both conducting and semi-insulating GaAs wafer , mechanical grade and epi ready grade are all available . We can offer GaAs wafer with low EPD value and high surface quality suitable for your MOCVD and MBE applications. PAM-XIAMEN can produce wide range grades: prime grade, test grade, and optical grade. Please contact our engineer team for more wafer information.


What is the GaAs Process?


GaAs wafers must be prepared prior to device fabrication. To start, they must be completely cleaned to remove any damage that might have occurred during the slicing process. The wafers are then Chemically Mechanically Polished/Plaranrized (CMP) for the final material removal stage. This allows for the attainment of super-flat mirror-like surfaces with a remaining roughness on an atomic scale. After that is completed, the wafer is ready for fabrication.
