Patent ID: 10032702

Abstract:
A package structure including a first redistribution circuitry and a second redistribution circuitry is provided. The first redistribution circuitry has a plurality of first top conductive pads and a plurality of first bottom conductive pads. A layout density of the first bottom conductive pads is greater than a layout density of the first top conductive pads. The second redistribution circuitry is disposed on the first redistribution circuitry and electrically connected to the first redistribution circuitry. The second redistribution circuitry has a plurality of second top conductive pads and a plurality of second bottom conductive pads. A layout density of the second bottom conductive pads is greater than a layout density of the second top conductive pads. Each of the second bottom conductive pads is directly coupled to a corresponding one of the first top conductive pads. A manufacturing method of a package structure is also provided.
