Abstract
An electronic device including an electronic unit and a redistribution layer is disclosed. The electronic unit has connection pads. The redistribution layer is electrically connected to the electronic unit and includes a first insulating layer, a first metal layer and a second insulating layer. The first insulating layer is disposed on the electronic unit and has first openings disposed corresponding to the connection pads. The first metal layer is disposed on the first insulating layer and electrically connected to the electronic unit through the connection pads. The second insulating layer is disposed on the first metal layer. The first insulating layer includes first filler particles, and the second insulating layer includes second filler particles. The first filler particles have a first maximum particle size, the second filler particles have a second maximum particle size, and the second maximum particle size is greater than the first maximum particle size.
