Abstract

PURPOSE:To mount the flip chip IC in smaller size by dividing the soldering bump into two parts on the IC chip and the circuit pattern and holding the latter bump with the soldering regist on the circuit pattern. CONSTITUTION:A soldering bump 12 is formed on a IC chip 11 through a plating or evaporating. A photosensitive regist 16 is laminated on a circuit substrate 15. Fine hole is provided through the regist at the position corresponding to the soldering bump 12 for a circuit pattern 14 by use of photographical process and then filled with a soldering bump 13. Bonding is effected by hot-melting the bumps 12 and 13. Since the bump 13 is held by the thick regist 16 at its circumference, the chip 11 is kept to be sufficcently high above the pattern 14 after hot-melting. Also, the bump 12 is formed to be so thin that there is no occurred a short circuit between the bumps. This enalbes to shorten the distance between the bumps significantly and thus to make the multi-pin type IC smaller in size.
