Abstract
A manufacturing method of integrated fan-out package includes following steps. First and second dies are provided on adhesive layer formed on carrier. Heights of first and second dies are different. First and second dies respectively has first and second conductive posts each having substantially a same height. The dies are pressed against adhesive layer to make active surfaces thereof be in direct contact with adhesive layer and conductive posts thereof be submerged into adhesive layer. Adhesive layer is cured. Encapsulant is formed to encapsulate the dies. Carrier is removed from adhesive layer. Heights of first and second conductive posts are reduced and portions of the adhesive layer is removed. First and second conductive posts are laterally wrapped by and exposed from adhesive layer. Top surfaces of first and second conductive posts are leveled. Redistribution structure is formed over adhesive layer and is electrically connected to first and second conductive posts.
