  • Patent number: 10461049
    Abstract: An aluminum electrode (2) is provided on a semiconductor device (1). A metallic film (3) for a solder joint is provided on the aluminum electrode (2). The organic protective film (4) is apart from the metallic film (3). An interval between the organic protective film (4) and the metallic film (3) is equal to or greater than half of a thickness of the organic protective film (4). Thus, even when the organic protective film (4) is deformed during sinter joining, the stress is not transmitted to the metallic film (3). Therefore, it is possible to prevent the solder connection metallic film (3) from cracking.
