US Patent 11508649 Semiconductor package including substrate with outer insulating layer

A semiconductor package may include a substrate and a semiconductor chip on the substrate. The substrate may include an inner insulating layer, a redistribution layer in the inner insulating layer, an outer insulating layer on the inner insulating layer, a connection pad provided in the outer insulating layer and electrically connected to the redistribution layer, and a ground electrode in the outer insulating layer. A top surface of the connection pad may be exposed by a top surface of the outer insulating layer, and a level of the top surface of the connection pad may be lower than a level of the top surface of the outer insulating layer. A level of a bottom surface of the ground electrode may be higher than a level of a top surface of the redistribution layer, and the outer insulating layer covers a top surface of the ground electrode.
