    Patent number: 8435376
    Abstract: Disclosed herein is a carrier for manufacturing a substrate, including: a base plate; adhesive layers formed on one side or both sides of the base plate; auxiliary adhesive layers, each of which is buried in one side of each of the adhesive layers, has a smaller area than each of the adhesive layers and has lower adhesivity than each of the adhesive layers; and metal layers, each of which is formed on one side of each of the auxiliary adhesive layers, whose edges are attached to the adhesive layers, and whose other portions excluding the edges are attached to the auxiliary adhesive layers. The carrier is advantageous in that a metal layer and an auxiliary adhesive layer are attached to each other by the adhesivity of the auxiliary adhesive layer, so that it is not required to use vacuum adsorption, with the result that a process of manufacturing a substrate can be performed more stably.

  • Mounting substrate and manufacturing method thereof
    Patent number: 8022553
    Abstract: A mounting substrate and a method of manufacturing the mounting substrate. The mounting substrate can include an insulation layer, a bonding pad buried in one side of the insulation layer in correspondence with a mounting position of a chip, and a circuit pattern electrically connected to the bonding pad. By utilizing certain embodiments of the invention, the process for stacking a solder resist layer can be omitted, as the bonding pads can be implemented in a form recessed from the surface of the insulation layer. In this way, the manufacturing process can be simplified and manufacturing costs can be reduced. Since the surface of the mounting-substrate on which to mount a chip can be kept flat without any protuberances, the occurrence of voids in the underfill can be minimized. This is correlated to obtaining a high degree of reliability, and leads to a greater likelihood of successful mounting.
