Abstract:
1. A method of manufacturing a semiconductor element-mounting board, comprising: arranging a plurality of conductive members in a mold; injecting an electrically insulating resin material into the mold after the conductive members are arranged therein so that the conductive members and the resin material are integrally molded to form a base member having a semiconductor element-mounting face and a circuit board-mounting face opposite the semiconductor element-mounting face, said arranging of the conductive members comprising orienting the conductive members in the mold so that the conductive members are substantially orthogonal to the semiconductor element-mounting face and the circuit board-mounting face and extend linearly through an interior of the base member between the semiconductor element-mounting face and the circuit board-mounting face, said injecting comprising injecting the resin material in an axial direction parallel to the longitudinal axes of the conductive members through at least two injection openings arranged symmetrically around each of the conductive members; mounting and electrically connecting a semiconductor element to the semiconductor element-mounting face by flip-chip mounting; and mounting and electrically connecting the circuit board-mounting face to a circuit board.
