A wafer boat is a precision packaging and handling component widely used in the semiconductor, electronics, and materials science industries. Specifically designed for storing, transporting, and protecting thin, fragile substrates—such as silicon wafers, compound semiconductor wafers (e.g., gallium arsenide, indium phosphide), glass substrates, or other precision circular/rectangular workpieces—it is suitable for scenarios including manufacturing, shipping, in-plant turnover, or sample delivery.
