Abstract

A manufacturing method of a package structure including the following steps is provided. A plurality of first conductive connectors and a second conductive connector on an active surface of a die are formed. The first conductive connectors are electrically connected to the die. The second conductive connector is formed aside the first conductive connectors and electrically insulated to the die. A redistribution layer is formed on the die. The redistribution layer is electrically connected to the first conductive connectors and the second conductive connector. A conductive shield is formed on the redistribution layer to surround the second conductive connector and at least a portion of a sidewall of the die coupled the active surface. The die is electrically insulated from the conductive shield. Another manufacturing method of a package structure is also provided.
