Abstract
A semiconductor device includes a semiconductor chip. A substrate is arranged in opposition to the semiconductor chip. A first electrode is placed on the semiconductor chip while a second electrode is placed on the substrate. Each of the first and second electrodes is made of the same electrode material. An intermetallic compound layer is formed between the first electrode and the second electrode. The intermetallic compound layer is entirely a binary alloy of the electrode material and a bonding material that was applied to at least one of the first and second electrodes.
