Wafer carriers are specialized containers designed to hold and protect semiconductor wafers during manufacturing and transportation. These carriers ensure that the delicate wafers, which are essential for producing microchips, remain free from contamination and physical damage. They are typically made from materials that are non-reactive and can withstand various environmental conditions. In the semiconductor industry, wafer carriers play a crucial role in processes such as photolithography and etching. They come in various sizes to accommodate different wafer diameters, commonly ranging from 200mm to 300mm. Proper handling and storage of wafers in these carriers are vital for maintaining the quality and yield of integrated circuits.
