Abstract: A carrier structure is provided, in which at least one positioning area is defined on a chip-placement area of a package substrate, and at least one alignment portion is disposed on the positioning area. Therefore, the precision of manufacturing the alignment portion is improved by disposing the positioning area on the chip-placement area, such that the carrier structure can provide a better alignment mechanism for the chip placement operation.
