[0024] 2A to 2G are schematic cross-sectional views of the manufacturing method of the chip electrical connection structure of the present invention.
[0025] As shown in FIG. 2A , firstly, at least one semiconductor chip 20 is provided, and conductive bumps 20 a are formed on the electrode pads 200 of the semiconductor chip 20 . The conductive bump 20a may be formed by any one of the conductive metal group consisting of copper, gold, silver, tin, nickel and palladium or formed by laminating multiple layers of the above metals. According to practical experience, the metal bump is preferably made of copper, but not limited thereto. In addition, the conductive bump can be formed by means of electroplating, physical deposition or chemical deposition. Since the manufacturing method is not the main technical feature of the present invention, it will not be repeated here.
[0026] As shown in FIG. 2B , at least one semiconductor chip 20 is mounted on a carrier 21 . The semiconduct...
