Abstract: 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.

Abstract: A method of fabricating the planar encapsulated surface is described. The substrate is provided, wherein a plurality of packaging units are formed thereon. The lower surface of the substrate is etched to form a trench between every two packaging units. The encapsulation adhesive material is filled to cover the lower surface of the substrate and the trench. A heatproof board is placed on the surface of the encapsulation material and the thermal process is performed to spread the encapsulation adhesive material out uniformly. The heatproof is removed to obtain a packaging structure having the planar surface.
