Y1 has a negative impact on the long-term reliability of Y1! It is one of the important processes that gives Traditionally,
The mainstream method for this was the eutectic method of AU-8i, in which the back surface of the chip 81 was hot-pressed to the Au-plated surface on the lead room.

。Some methods using solder have been put into practical use, but it has been pointed out that the solder and solder balls may scatter and adhere to electrodes, etc., causing corrosion and disconnection. On the other hand, in the method of using conductive adhesive, an epoxy resin containing A<J powder is usually used, and it has been partially put into practical use for about 10 years, but in terms of reliability, △u- Compared to the eutectic method that produces 3i eutectic, there was no satisfactory result1.
When using conductive T4I adhesive, it has advantages over soldering (such as superior heat resistance), but it is difficult to use because the resin and its curing agent are not made for bonding semiconductor devices. In many cases, the corrosion of the AI electrode is promoted and the IIJi wire is defective in one car, and the reliability of the element is reduced to Δu-3i.
It was inferior to the Kyodo Law. Furthermore, in the case of semiconductor devices using conventional conductive adhesives, there is a problem in that the VF characteristics may deteriorate due to differences in the manufacturing process of the device.
