Abstract
A semiconductor device with thin redistribution layers is disclosed and may include forming a first redistribution layer on a dummy substrate, electrically coupling a semiconductor die to the first redistribution layer, and forming a first encapsulant layer on the redistribution layer and around the semiconductor die. The dummy substrate may be removed thereby exposing a second surface of the first redistribution layer. A dummy film may be temporarily affixed to the exposed second surface of the redistribution layer and a second encapsulant layer may be formed on the exposed top surface of the semiconductor die, a top surface and side edges of the first encapsulant layer, and side edges of the first redistribution layer. The dummy film may be removed to again expose the second surface of the first redistribution layer, and a second redistribution layer may be formed on the first redistribution layer and on the second encapsulant layer.
