A method of manufacturing a circuit board, which includes a bump pad on which a solder bump may be placed, may include forming a solder pad on a surface of a first carrier; forming a metal film, which covers the solder pad and which extends to a bump pad forming region; forming a circuit layer and a circuit pattern, which are electrically connected with the metal film, on a surface of the first carrier; pressing the first carrier and an insulator such that a surface of the first carrier and the insulator faces each other; and removing the first carrier. Utilizing this method, the amount of solder for the contacting of a flip chip can be adjusted, and solder can be filled inside the board, so that after installing a chip, the overall thickness of the package can be reduced.

摘要:
A method of manufacturing a board on chip package including laminating a dry film on a carrier film, one side of which is laminated by a thin metal film; patterning the dry film in accordance with a circuit wire through light exposure and developing process, and forming a solder ball pad and a circuit wire; removing the dry film; laminating an upper photo solder resist excluding a portion where the solder ball pad is formed; etching the thin metal film formed on a portion where the upper photo solder resist is not laminated; mounting a semiconductor chip on the solder ball pad by a flip chip bonding; molding the semiconductor chip with a passivation material; removing the carrier film and the thin metal film; and laminating a lower photo solder resist under the solder ball pad. The board on chip package provides a high density circuit since a circuit pattern is formed using a seed layer.
