A fabricating method of an embedded package structure includes following steps. First and second boards are combined to form an integrated panel. First and second circuit structures are respectively formed on the first and second boards that are then separated. An embedded element is electrically disposed on the first circuit structure. First and second conductive bumps are respectively formed on a conductive circuit substrate and the second circuit structure. First and second semi-cured films are provided; a laminating process is performed to laminate the first circuit structure on the first board, the first and second semi-cured films, the conductive circuit substrate, and the second circuit structure on the second board. The first and second semi-cured films encapsulate the embedded element. The first and second conductive bumps respectively pierce through the first and second semi-cured films and are electrically connected to the first circuit structure and the conductive circuit substrate, respectively.

Fabricating method of embedded package structure

A fabricating method of an embedded package structure is provided. The method includes combining a first board and a second board to form an integrated panel; forming a first circuit structure on the first board and forming a second circuit structure on the second board; separating the first board from the second board; electrically disposing an embedded element on the first circuit structure; forming at least one conductive bump on the second circuit structure; and providing a semi-cured film and performing a laminating process to laminate the first circuit structure on the first board, the semi-cured film, and the second circuit structure on the second board, wherein the semi-cured film encapsulates the embedded element, and after the laminating process is performed, the at least one conductive bump pierces through the semi-cured film and is electrically connected to the first circuit structure.
