The present invention provides a chip packaging structure and a chip packaging method. The chip packaging structure includes a substrate, a metal bonding pad disposed on the substrate and a metal wire, wherein the tail end of the metal wire is provided with a welding part, the welding part is welded to the metal bonding pad, the metal bonding pad is provided with a coating layer, and at least part of the welding part is located between the coating layer and the metal bonding pad. The present invention greatly improves a welding effect of the metal wire and the metal bonding pad, so that the welding of the metal wire and the metal bonding pad is more reliable and stable.

The present invention relates to a structure for packaging and the method for manufacturing the same. The structure for packaging comprise two or more metal members disposed on a substrate or a semiconductor device. A patterned layer and an insulation layer are disposed surrounding the metal members. There is a gap between the patterned layer and the insulation layer. Thereby, while bonding the metal members, metal spilling can be avoided, for further preventing the structure from short circuit or current leakage.
