Abstract: An electronic device is provided. The electronic device includes a chip, a redistribution structure, a contact pad, a buffer layer, and a first connection pad. The redistribution structure is electrically connected to the chip. The redistribution structure includes a metal pad, and the metal pad is disposed opposite to the chip. The contact pad is disposed on the metal pad. The buffer layer is disposed on the redistribution structure and includes an opening. The opening exposes at least a portion of the contact pad. The first connection pad is disposed on the contact pad and extends in the opening. Moreover, in a normal direction of the chip, the metal pad, the contact pad and the first connection pad overlap. A method of manufacturing an electronic device is also provided.
