Abstract

PURPOSE:To prevent crack at the junction by making equal the diameter of copper bump projecting on a semiconductor chip and that of conductor layer on a substrate which is set opposite to this bump. CONSTITUTION:A cylindrical copper bump 21 which is the terminal electrode of circuit elements formed on a silicon chip 11 projects at the position opposing to a conductor layer 14 formed on a substrate 12. And a soldering member 22 connecting the conductor layer 14 to the bump 21 encloses the outer periphery of bump 21 and the bump 21 is enclosed within the soldering member 22. At this time, the ratio of diameter of the bump 21 to that the conductor layer 14 is set to '1+ or -0.3'. By making equal the bump diameter and the conductor layer diameter, the maximum distortion in the soldering member connecting the both can be minimized. It prevents crack produced at the junction.
