摘要:
Disclosed herein are a semiconductor package and a method for manufacturing the same. The method includes preparing a substrate having one surface and the other surface; mounting a semiconductor device mounted on one surface of the substrate; forming external connection terminals on the other surface of the substrate; forming a warpage preventing layer formed on one surface of the substrate or the other surface of the substrate; and performing a reflow process on the substrate.

A metal core package substrate and a method for manufacturing the same. A method for manufacturing a metal core package substrate may include: forming a plurality of holes in a metal core; forming a plurality of paste bumps piercing into insulation layers of a first copper foil layer and a second copper foil layer; positioning the first and second copper foil layers at positions corresponding to the holes of the metal core so that the paste bumps are opposed to each other around the metal core; allowing each paste bump to pierce into the holes of the metal core by pressing the first and second copper foil layers; and forming inner circuits in the metal core pierced with the paste bumps.

Disclosed herein is a carrier for manufacturing a substrate, including: two insulation layers, each being provided on one side thereof with a first metal layer and on the other side thereof with a second metal layer; and a third metal layer having a lower melting point than the first metal layer and formed between the two first metal layers respectively formed on the two insulation layers such that the two first metal layers are attached to each other. The carrier is advantageous in that the carrier can be separated by heating the third metal layer, so that the size of a substrate does not change at the time of separating the carrier, thereby maintaining the compatibility between a substrate and manufacturing facilities.

Disclosed are a carrier substrate including an insulating base material with a copper foil layer formed on at least one surface thereof, a metal layer formed on the copper layer and having a length shorter than that of the copper foil layer, and an insulating layer formed on the metal layer, a fabrication method thereof, a printed circuit board (PCB) using the same, and a fabrication method thereof. Because there is no land at the via and core in the substrate, because a circuit pattern connected with the via can be formed to be finer, so the circuit pattern can be highly integrated and the substrate can become thinner. Thus, a printed circuit board (PCB) having a smaller size and reduced number of layers can be fabricated.

Disclosed herein is a carrier for manufacturing a printed circuit board, including: a magnetic sheet; and a metal layer attached to at least one side of the magnetic sheet by magnetic properties of the magnetic sheet. The carrier is advantageous in that its structure can be simplified without performing a vacuum or releasing process at the time of the attachment and separation of the carrier, thus reducing process cost and process time and maintaining the size of a printed circuit board.

Disclosed herein is a method for manufacturing a semiconductor package which uses a base member 120 in which a first metal layer 113, a barrier layer 115, and a second metal layer 117 are stacked on both surface thereof in sequence based on an adhesive member 111 to simultaneously manufacture two printed circuit boards through a single sheet process, thereby making it possible to improve manufacturing efficiency; electrically connects a semiconductor chip 300 to a printed circuit board through a solder bump 250, thereby making it possible to implement a high-density package substrate; and forms a metal post 140 instead of a through hole to required in an interlayer circuit connection, thereby making it possible to reduce costs required in the processing/plating of the through hole.

Disclosed herein is a carrier for manufacturing a substrate, including: an insulation layer including a first metal layer formed on one side or both sides thereof; a second metal layer formed on one side of the first metal layer; and a third metal layer formed on one side of the second metal layer, wherein the second metal layer has a lower melting point than the first metal layer or the third metal layer. The carrier is advantageous in that a build up layer can be separated from a carrier by heating, so that a routing process is not required, with the result that the size of a substrate does not change when the build up layer is separated from the carrier, thereby reusing the carrier and maintaining the compatibility between the substrate and manufacturing facilities.
