A packaging substrate and a method of manufacturing the same are provided. The method includes following steps. First, a first substrate including at least one defected packaging unit and several first packaging units is provided. The defected packaging unit and the first packaging units are arranged in an array on the first substrate. Next, the defected packaging unit is removed from the first substrate to correspondingly form at least one opening in the first substrate. Then, a second substrate including at least one second packaging unit is provided. Later, the second packaging unit is separated from the second substrate. The area of the second packaging unit is less than that of the opening. Subsequently, the second packaging unit is disposed in the opening. The edge of the second packaging unit is placed partially against an inner wall of the opening.

A flip chip package process is provided. First, a substrate strip including at least one substrate is provided. Next, at least one chip is disposed on the substrate, and the chip is electrically connected to the substrate. Then, a stencil having at least one opening and an air slot hole is disposed on an upper surface of the substrate strip, an air gap is formed between the stencil and the substrate strip, the air gap connects the opening and the air slot hole, and the chip is located in the opening. Finally, a liquid compound is formed into the opening of the stencil to encapsulate the chip, and a vacuum process is performed through the air slot hole and the air gap, so as to prevent the air inside the opening from being encapsulated by the liquid compound to become voids.

The present invention relates to a stackable package having an embedded interposer and a method for making the same. The package includes a substrate, a chip, a first embedded interposer, a circuit layer and a solder mask. The substrate has an upper surface, a bottom surface and at least one connecting pad. The connecting pad is disposed adjacent to the upper surface. The chip is disposed adjacent to the upper surface of the substrate, and is electrically connected to the substrate. The first embedded interposer encapsulates the upper surface of the substrate and the chip. The to first embedded interposer includes at least one plating through hole. The plating through hole penetrates through the first embedded interposer, and is connected to the connecting pad of the substrate. The circuit layer is disposed adjacent to the first embedded interposer, and the plating through hole is connected to the circuit layer. The circuit layer includes at least one pad. The solder mask is disposed adjacent to the circuit layer, and exposes the pad. Therefore, the package has more pads for inputting/outputting, more flexibility for stacking a top package, and a reduced total thickness.

A circuit structure of a redistribution layer (RDL) is suitable for a chip to define the circuits and the contact window required by the following bump process. The RDL is disposed on the active surface of the chip. The circuit structure of the RDL mainly includes a first titanium layer, a second titanium layer and a conductive layer. Wherein, the conductive layer is made of aluminum; the first titanium layer and the second titanium layer cover the two surfaces of the conductive layer, respectively. The connectivity between the first titanium layer or the second titanium layer and a macromolecule polymer is stronger than the connectivity between the conductive layer and the macromolecule polymer, so that the peeling or crack caused by poor connectivity between the conductive layer and the adjacent dielectric layers are significantly improved thereby.
