    Abstract: Methods of fabricating a semiconductor package may include forming a first barrier layer on a first carrier, forming a sacrificial layer, including an opening that exposes at least a portion of the first barrier layer, on the first barrier layer, and forming a second barrier layer on the first barrier layer and on the sacrificial layer. The second barrier layer may include a portion formed on the sacrificial layer. The methods may also include forming a first insulating layer in the opening and protruding beyond a top surface of the portion of the second barrier layer on the sacrificial layer, a top surface of the first insulating layer being farther from the first barrier layer than the top surface of the portion of the second barrier layer, forming a redistribution structure including a redistribution layer and a second insulating layer on the first insulating layer and on the second barrier layer, mounting a semiconductor chip on the redistribution structure, attaching a second carrier onto the semiconductor chip and removing the first carrier, removing the first barrier layer, the sacrificial layer, and the second barrier layer to expose portions of the redistribution structure, and forming solder balls, respectively, on the portions of the redistribution structure.

    Abstract: A package substrate, a semiconductor package having the same, and a method for fabricating the semiconductor package. The semiconductor package includes a semiconductor chip, a package substrate, and a molding layer. The package substrate provides a region mounted with the semiconductor chip. The molding layer is configured to mold the semiconductor chip. The package substrate includes a first opening portion that provides an open region connected electrically to the semiconductor chip and extends beyond sides of the semiconductor chip to be electrically connected to the semiconductor chip.

    Abstract: A semiconductor package includes a first substrate including a circuit pattern and a dummy pattern on an upper face of the first substrate, a solder ball, a second substrate on the first substrate, and an underfill material layer between the first and second substrates. The underfill material layer wraps around the solder ball. The dummy pattern is not electrically connected to the circuit pattern. The first substrate includes a solder resist layer on the circuit pattern and the dummy pattern. The solder resist layer includes a first opening for exposing at least a part of the circuit pattern. The solder ball is in the first opening and electrically insulated from the dummy pattern by the solder resist layer. The second substrate is electrically connected to the first substrate by the solder ball. The second substrate is electrically insulated from the dummy pattern by the solder resist layer.
