  • Patent number: 7948085
    Abstract: A circuit board structure and a fabrication method of the same are disclosed according to the present invention. The circuit board structure includes: a carrier board with at least one surface formed with a circuit layer having electrically connecting pads; a first solder mask formed on the carrier board and the circuit layer and formed with first openings for exposing the electrically connecting pads; and a second solder mask formed on the first solder mask and formed with second openings for exposing the first openings and the electrically connecting pads. The first solder mask is made of a high-insulation photosensitive material characterized by presence or absence of impurities, such as microparticles, to have enhanced fluidity for being filled in the circuit layer, thereby preventing metal ions migration and subsequent metal hypha electricity discharge which might otherwise affect electrical performance, therefore the present invention is applicable to fine circuit fabrication.

  • Patent number: 7554131
    Abstract: A chip embedded package structure and a fabrication method thereof are proposed. An adhesive layer is formed on a bottom surface of a carrier board having at least one cavity to seal one end of the cavity. At least one semiconductor chip is mounted via its non-active surface on the adhesive layer and received in the cavity. A protection layer is formed on an active surface of the semiconductor chip. A conductive layer is formed on a top surface of the carrier board, the protection layer and the cavity. A patterned resist layer is applied on the conductive layer and is formed with an electroplating opening at a position corresponding to a gap between the cavity and the semiconductor chip. An electroplating process is performed to form a metal layer in the electroplating opening, such that the semiconductor chip can be effectively fixed in the cavity by the metal layer.
