Abstract

PURPOSE:To absorb thermal expansion difference between a semiconductor element and a wiring board and to prevent a connection from disconnecting due to a thermal hysteresis by increasing the length of a solder post for bonding the element to the board. CONSTITUTION:A metal layer 12 disposed at four corners of a semiconductor element 11 is dipped in a melted eutectic solder bath to form a solder semisphere 13. The sphere 13 is also formed in the same manner as before on the copper foil pattern 14 of a wiring board 15. Then, the board 15 faces oppositely the element 11, the substrate is heated and held at 150 deg.C, the sphere 13 is melted by irradiating an infrared ray from the element side to form a drum-like solder 13. Thereafter, the element is raised to control an interval between the element and the board to stop the irradiation of the infrared ray, air-cooled to prepare a solder post 13 exhibiting slender and thick drum-like columnar state.
