Method of manufacturing a semiconductor device having a chip mounted on an interposer

A method for manufacturing a semiconductor device, comprising the steps of:

• mounting via an adhesive, a second semiconductor chip of a second semiconductor package on an upper surface of a first molding resin of a first semiconductor package, the second semiconductor chip being mounted to a second interposer of the second semiconductor package by flip-chip bonding, wherein the adhesive is provided directly on the second semiconductor chip;
• sealing an area between the first molding resin and the second interposer by filling the area between the first molding resin and the second interposer with a supporting member so as to cover side surfaces of the second semiconductor chip;
• and
• forming, on an upper surface of a first interposer comprised in the first semiconductor package, a second molding resin that surrounds and seals the first molding resin, which surrounds and seals a first semiconductor chip of the first semiconductor package, and surrounds and seals side surfaces of the supporting member that covers the side surfaces of the second semiconductor package.
