Abstract

The invention discloses a chip packaging structure and method, and the method comprises the following steps: installing a first chip and a first element assembly on a first surface of a substrate; installing a cover body structure on the first surface to enable the cover body structure to cover the first element assembly; carrying out plastic package on the first surface of the substrate to form afirst pre-plastic package layer, the first chip and the cover body structure being located in the first pre-plastic package layer; and cutting the first pre-plastic package layer, the cover body structure and the substrate to expose the first element assembly to obtain a first plastic package layer in which the first chip is located. A common mold can be adopted in the plastic packaging process,a special-shaped mold does not need to be used, the mold opening cost and the mold opening time of the mold can be greatly reduced, the dispensing process is easy to control, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of semiconductor packaging, in particular to a chip packaging structure and packaging method. Background technique [0002] Packaging technology is a technology that packs integrated circuits with insulating plastic or ceramic materials. Packaging technology is necessary and crucial for chips, because chips must be isolated from the outside world to prevent impurities in the air from affecting the chips. Corrosion of the circuit causes electrical performance degradation. [0003] The connector components in the packaging structure or the sensor components that need to be in contact with the outside need to be exposed to connect with external components. For the packaging structure that some components need to be exposed, it is generally packaged with a special-shaped mold, and the special-shaped mold is designed as a bump on the part that needs to be exposed , to block the filling of plastic sealing compound, but the...
