  • Patent number: 12713968
    Abstract: A fan-out wafer-level packaging structure and a method for manufacturing it are disclosed. The structure includes: a rewiring layer, a chip, an electrical component, a protective layer made of UV-curable adhesive, a molding layer, and a solder ball. The protective layer is disposed on surfaces of the electrical component, sealing the electrical component, and ensuring its safe operation and reliability, mitigating risks of melting and spillage of solder in the electrical component, and preventing electrical shorts and delamination between molding layers and the electrical component. The protective layer is formed by UV-curing or UV/thermal-dual-curing, to prevent loss of upper portions of the adhesive resulted from the upper portions flowing downward after dispensing. A dual-curing process can further solidify the protective layer, enabling the protective layer to better seal and protect the electrical component.
