。Next, as shown in FIG. 1(d), the transfer substrate 1 is peeled off at the interface between the insulating film 3 and the resin 8, and the protruding electrodes 4 are transferred to the electrode 7 side of the semiconductor element 6. At this time, if acrylic is used instead of Teflon resin for the insulating film 3, the adhesive strength between Teflon and acrylic is weak and can be easily peeled off. Furthermore, if a film-like material is used as the transfer substrate 1, it is possible to use the transfer substrate 1 as shown in FIG.
As shown in C), it can be easily peeled off by beading. At this time, the area of the protruding electrode 4 that is bonded to the resin 8 is larger than the area of the area that is in contact with the transfer substrate 1. Since the area is sufficiently large, the protruding electrode 4 is peeled off at the interface with the metal film 2. In addition, iTo is added to the metal film 2.
If or Or f is used, the adhesion with the protruding electrodes made of Au, Cu, etc. will be poor, and the releasability of the protruding electrodes 4 will be improved. In addition, the transfer substrate 1 on which the protruding electrodes 4 have been transferred to the semiconductor element 6 side can be plated again to form the protruding electrodes, and the metal film 2 and the insulating film 3 are once formed. By repeating plating,
Can be used semi-permanently. Thus, according to the present invention,
Protruding electrodes can be easily formed without special processing such as vapor deposition or etching on semiconductor elements as in the past, and the transfer substrate can be used semi-permanently by repeating the plating process only. The cost will be extremely low.

At this time, the resin 8' was injected after the semiconductor element was installed on the aft wiring board.
It may be applied to the semiconductor element 6 or the wiring board 11 before installation. The resin 8' is made of epoxy, silicone, acrylic, etc., and may be cured by any of photocuring, room temperature curing, and heat curing. In this way, the semiconductor element 6
Since the connection with the wiring board 11 is made by pressure contact via the protruding electrode 4, there is a great degree of freedom in selecting the material for the wiring 12.
