Abstract

A semiconductor structure and a manufacturing method thereof are provided. The semiconductor structure includes a redistribution structure, a circuit substrate, and an insulating encapsulation. The redistribution structure includes a first under-bump metallization (UBM) pattern covered by a first dielectric layer, and the first UBM pattern includes a surface substantially leveled with a surface of the first dielectric layer. The circuit substrate is electrically coupled to the redistribution structure through a conductive joint disposed on the surface of the first UBM pattern. The insulating encapsulation is disposed on the redistribution structure to cover the circuit substrate.
