Abstract

PURPOSE:To prevent the outflow of solder at the thermo compression bonding of a bump electrode, by filling the concave part formed on the surface of high melting point metal with a semiconductor flip chip element bump electrode with low melting point metal serving as solder. CONSTITUTION:After a surface protecting film 4 is adhered on an Al wiring 3 connected to an Si substrate 1 by an Si oxide film 2 window 2a on the Si substrate 1, a window 4a is provided on this surface protecting film 4 to form a bump electrode on this window part. The bump electrode forms a base metallic layer 5 constituted of three layers of Ti-Cu-Ni or Cr-Cu-Ni, etc. with a high melting point metal 9 of Au, etc. by electroplating with a photoresist as a mask thereon. Thereat, an electrodeposition condition is controlled to raise the fringe thereof 9a in abnormal growth next for the electrodeposition of low melting point metal 10 of Sn, etc. serving as solder within the fringe 9a.
