发明名称 Chip packaging structure and method of making wafer level packaging
摘要 The present invention provides a chip packaging structure and method of making wafer level packaging. Chip packaging structure comprises a chip, a dam formed surrounding the perimeter of the chip, and a frame glue coated over the surface of the dam. A transparent cover is formed on the top of the frame glue and adhered against the dam by the frame glue. A sealed space is formed between the transparent cover and the chip. The method of making wafer level packaging comprises the steps of: providing a wafer having a plurality of chip patterns thereon; forming a plurality of dams on the wafer and forming each dam surrounding each chip pattern; coating a frame glue over the surface of each dam; covering the transparent cover over the frame glue to form a plurality of sealed spaces between the transparent cover and the wafer, wherein each sealed space comprises a chip pattern; and dicing the chip patterns over the wafer as units in form a plurality of chip packaging structures. The present invention has highly reliability, high yield of luminous flux and photosensitive, simple manufacturing process and adhering frame glue uniformly.
