Abstract
PURPOSE:To make it possible to easily form a bump of a uniform height by a method wherein the surface of a supporting member which is conductive except its recessed part is electrified, electric charge is accumulated at the recessed part only, microscopic metal particles are scattered on the surface of the supporting member, the metal particles are retained by the electrostatic force of the recessed part, and they are transferred to the electrode of an IC. CONSTITUTION:A supporting member 11, having a recessed part 12 on the part corresponding to the electrode pad of an electronic part chip 15 and also having conductivity on the surface excluding the recessed part 12, is prepared. Then, said supporting member 11 is charged, microscopic metal particles 14 are retained in the recessed part 12 by electrostatic force, they are transferred to the electrode 15a of an electronic part chip 15, and a bump electrode is formed on the electrode 15a of the semiconductor chip 15 without conducting a plating treatment, the control of which is difficult. As a result, the measurements of the bump electrode, especially uniform height, can be formed easily.
