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.
