Abstract

The present invention discloses a package structure for reducing warpage of plastic package wafer, including an adapter board, a chip mounted on the adapter board, and a first plastic package layer covering the chip, through-silicon-vias are disposed on the adapter board, the first and second surfaces of the adapter board are respectively provided with external connection solder balls and/or external connection solder pads electrically connected with the through-silicon-vias. The process of manufacturing the package structure includes: after the first surface process of the adapter board is completed, bonding the first carrier on its first surface, then cutting the first carrier to expose the chip-mounting area, and then carrying out subsequent processes such as chip mounting, and finally cutting and removing the first carrier to complete the package.
