Abstract
The present disclosure provides a wafer-level ASIC 3D integrated substrate, a packaging device and a preparation method. The substrate includes a first wiring layer, conductive pillars, a molding layer, a second wiring layer and solder balls. The first wiring layer includes a first dielectric layer and a first metal wire layer, the first metal wire layer is exposed from a top surface of the first dielectric layer. The second wiring layer includes a second dielectric layer and a second metal wire layer. The conductive pillars are disposed between the first wiring layer and the second wiring layer, two ends of each conductive pillar are electrically connected to the first metal wire layer and the second metal wire layer, respectively. The molding layer molds the conductive pillars. The solder balls are disposed on a side of the second wiring layer and electrically connected to the second metal wire layer.
