Abstract

The present disclosure provides a wafer-level chip scale packaging structure and a method for manufacturing the same. The method includes the following steps: 1) providing a first supporting substrate; 2) placing a first chip on the first supporting substrate, and forming a first packaging layer on the first chip; 3) separating the first chip and the surface of the first packaging layer in contact with the first chip from the first supporting substrate, and attaching the other surface of the first packaging layer to a second supporting substrate; 4) disposing a second packaging layer on the surface of the first packaging layer which is in contact with the first chip; 5) forming a rewiring layer on the second packing layer, the rewiring layer is electrically connected to the first chip; and 6) electrically connecting a second chip to the rewiring layer.
