Abstract:
A substrate structure includes a substrate body, a bottom circuit layer, a first bottom protection structure and a second bottom protection structure. The substrate body has a top surface and a bottom surface opposite to the top surface. The bottom circuit layer is disposed adjacent to the bottom surface of the substrate body, and includes a plurality of pads. The first bottom protection structure is disposed on the bottom surface of the substrate body, and covers a portion of the bottom circuit layer. The second bottom protection structure is disposed on the bottom surface of the substrate body, and covers a portion of the bottom circuit layer. A second thickness of the second bottom protection structure is greater than a first thickness of the first bottom protection structure.
