Abstract
A semiconductor package device includes a wiring structure, a semiconductor chip and an encapsulant. The semiconductor chip is electrically connected to the wiring structure. The encapsulant is disposed on the wiring structure and covers the semiconductor chip. A roughness (Ra) of a surface of the encapsulant is about 5 nm to about 50 nm.
