Wafer tape is a special adhesive tape used in semiconductor manufacturing. Its primary function is to protect the surface of wafers, preventing contamination and damage. It allows wafers to be safely transported and handled during manufacturing, from one process to another, or from the wafer to individual chips after dicing. Wafer tape is designed to withstand chemical substances and temperature variations, ensuring that wafers remain intact and clean throughout the manufacturing process. This contributes to higher production efficiency and product quality assurance.
