Technical Field
[0001] The utility model relates to a storage device for single crystal silicon wafer production, belonging to the technical field of single crystal silicon wafers. Background Technique
[0002] Single crystal silicon wafers are thin wafers made of high-purity single crystal silicon materials and are the core materials in modern semiconductor and photovoltaic industries. Through a precise crystal pulling process, silicon is melted at high temperature and then slowly cooled and stretched to form a silicon rod with a single crystal structure, which is then cut into thin wafers to obtain single crystal silicon wafers. Due to its continuous crystal structure without impurities or grain boundaries, single crystal silicon wafers have excellent electronic properties and are widely used in the manufacture of integrated circuits, solar cells, and other high-performance electronic devices. In the photovoltaic industry, single crystal silicon wafers have gradually become the mainstream material for solar cell production due to their high efficiency and stability.
[0003] In the production of single crystal silicon wafers, a storage device is needed to store them. However, the existing storage devices usually place multiple single crystal silicon wafers in a storage tank, which lacks a limiting structure. During transportation, the single crystal silicon wafers are prone to shaking. Since single crystal silicon wafers are relatively fragile, they may break during the shaking process, resulting in waste of resources.
[0004] Therefore, a storage device for single crystal silicon wafer production is proposed. Content of the Utility Model
