According to this embodiment, not only conventional flip-chip mounting is possible, but also mounting with a short process time (tact) is possible. In other words, instead of applying heat to harden the conductive resin as in the past when flip-chip mounting, insert the gold bump with the conductive resin at room temperature into the electrode pad of the corresponding substrate, and seal the resin. After sealing the conductive resin, the conductive resin is cured simultaneously with the curing of the sealing resin. This prevents contact deviation between the substrate and the semiconductor chip, and eliminates the need to wait for the conductive resin to cure, thereby reducing tact time.

In the substrate 10 shown in FIG. 1, the holes 14 of the electrode pads are formed as through holes, but may be formed as bottomed holes as shown in FIG. This allows the mounting without the tip of the gold bump piercing the base material.

Further, as shown in FIG. 4, the holes 14 of the electrode pads may be formed as through holes, and the holes 15 may be formed in the base material 11 so that the gold bumps can be inserted deeply. This substrate can be mechanically connected without using a conductive resin by fitting the tip of the convex portion of the gold bump into the hole of the base material.

Further, as shown in the substrate of FIG. 5, not only the hole 14 for inserting the gold bump but also a hole 16 for increasing the bonding area between the resin and the electrode pad may be provided.
By providing the hole 16 into which the resin flows, the connection area between the electrode pad of the substrate and the conductive resin increases, and the connection reliability improves.

According to the present invention, since the connection area between the electrode pad of the substrate and the conductive resin increases, the peeling does not easily occur at the interface between the electrode pad of the substrate and the conductive resin, and the reliability of the connection portion is reduced. To improve.

Also, since the mounting temperature is lower than that of the conventional method using solder, the stress between the gold bump and the electrode pad of the semiconductor chip due to the difference in thermal expansion between the substrate and the semiconductor chip can be reduced. In addition, it is possible to reduce the defect that the electrode pad of the chip is cracked.

Further, the cost is reduced by shortening the manufacturing time. In other words, since the tip of the gold bump is mechanically connected to the electrode pad of the substrate, there is no need to worry about the displacement of the contact between the substrate and the chip. Can be filled with a sealing resin. Therefore, the tact can be shortened by the curing time of the conductive resin, which leads to cost reduction.
