A semiconductor package structure includes a redistribution structure, a chip, an upper dielectric layer, a plurality of conductive members and an encapsulation layer. The redistribution structure includes a redistribution layer and a first dielectric layer disposed on the redistribution layer. The upper dielectric layer is disposed between the chip and the first dielectric layer of the redistribution structure, wherein the upper dielectric layer and the first dielectric layer are organic materials. A plurality of conductive members is disposed between the redistribution layer and the chip. Each conductive member has a first end adjacent to the chip and a second end adjacent to the redistribution structure, wherein the first end of said each conductive member contacts with the upper dielectric layer and the second end of said each conductive member contacts with the first dielectric layer.

Semiconductor package structure

A redistribution layer structure of the semiconductor package includes a dielectric layer having a thickness, at least one upper conductive wire disposed on a first surface of the dielectric layer, at least one lower conductive wire disposed on a second surface of the dielectric layer, and vias penetrating the dielectric layer and connecting the at least one upper conductive wire and the at least one lower conductive wire. Each via has a cross-section at one upper conductive wire. The cross-section has a third width. The ratio of the third width to the thickness of the dielectric layer is less than or equal to 1. The ratio of the pitch between every two adjacent vias to the third width is greater than or equal to 0.5.
