(Prior Art) As a surface mounting package, a chip carrier as shown in FIG. 4 or a flat package as shown in FIG. 5 is known. In recent years, semiconductor devices have been highly integrated, and accordingly, a large number of input / output terminals are required for a package for mounting this type of semiconductor device.

In the conventional chip carrier and flat package, the input / output terminals are arranged only on the outer periphery of the base material on which the semiconductor elements are mounted. When the number of input / output terminals exceeds 200, the area of the package becomes large and the printed wiring board There is a problem that the mounting density is reduced. For such a package with a high number of terminals, the pin grid array as shown in FIG. 6 is suitable.

At the same time, a connection failure will occur at that portion. In order to solve such a problem, a chip carrier mounting method as shown in FIG. 8 is disclosed. (JP-A-60-8994) This is a chip carrier (21) and a printed wiring board (31).
And a metal member (2) having a height or particle size smaller than that of the connecting solder (22) and a melting point higher than that of the solder (22).

(Problems to be Solved by the Invention) The present invention has two problems described above, that is, in the conventional chip carrier, since the input / output terminals are arranged only on the outer periphery of the base material, a large number of input / output terminals are provided. If it is necessary, the problem that the mounting density on the printed wiring board decreases, and in the mounting method on the printed wiring board, in the conventional method, the conductor pad on the chip carrier side and the corresponding printed wiring board side Since the conductor pads are directly joined by soldering, the difference in thermal expansion coefficient and thermal capacity between the chip carrier and the printed wiring board causes physical failure of the joining solder due to heat generation during operation of the semiconductor chip, which is likely to cause connection failure. It aims to solve both problems and problems at the same time.
