[Technical background of the invention and its problems] In the manufacturing of semiconductor devices, there is a process (mounting process) of electrically connecting semiconductor chips such as IC, L, SI, etc. to a predetermined part on a thin metal plate (lead frame). is one of the important steps that affect the long-term reliability of semiconductor devices. Conventionally, the mainstream method for this connection has been the Au-8i eutectic method, in which the Si surface on the back of the chip is heated and pressure-bonded to the Au plating surface on the lead frame. However, with the rise in the prices of precious metals, especially A and U, in recent years, resin-molded semiconductor devices have rapidly shifted from the Al1-3i eutectic method to methods that use solder and conductive adhesives. It's coming.

On the other hand, the method of using conductive adhesive, which usually uses epoxy resin mixed with Ag powder, has been partially put into practical use for about 10 years, but it produces a eutectic alloy of Au-8i. Compared to the eutectic method, there was no satisfactory reliability in terms of reliability. In addition, this method has advantages such as superior heat resistance compared to the soldering method, but because the resin and its curing agent are not made for bonding semiconductor elements, it has inferior moisture resistance. This often promotes corrosion of the aluminum electrode and causes disconnection defects, and the reliability was still inferior to the Au-8i eutectic method.
