Abstract
Provided are a semiconductor package and a method of fabricating the same. The semiconductor package includes a semiconductor chip, and a plurality of conductive balls, e.g., solder balls formed on a joint surface of the semiconductor chip. A dummy board includes openings aligned with the solder balls and is bonded to the joint surface of the semiconductor chip. An adhesive material is interposed between the semiconductor chip and the dummy board to adhere the dummy board to the semiconductor chip. The adhesive material is applied on an adhesion surface of the dummy board adhered to a joint surface of the semiconductor chip. The dummy board is adhered to the joint surface of the semiconductor chip such that the solder balls are aligned with the openings. Cheap underfill materials can be selectively used, and a process time for reflow and curing of the adhesive material can be greatly reduced.
