Abstract

A semiconductor package and a manufacturing method thereof are provided. The semiconductor package includes a first semiconductor device, at least one second semiconductor device, at least one dummy die, an encapsulant and a redistribution structure. The first semiconductor device, the at least one second semiconductor device and at least one dummy die are laterally separated from one another, and laterally encapsulated by the encapsulant. A Young's modulus of the at least one dummy die is greater than a Young's modulus of the encapsulant. A sidewall of the at least one dummy die is substantially coplanar with a sidewall of the encapsulant. The redistribution structure is disposed over the encapsulant, and electrically connected to the first semiconductor device and the at least one second semiconductor device.
