发明名称 Mounted structure
摘要 A mounted structure includes an electrode of a substrate, an electrode of a semiconductor element, and a mounted layers for bonding the electrode of the substrate and the electrode of the semiconductor element, and the mounted layers includes: a first intermetallic compound layer containing a CuSn-based intermetallic compound; a Bi layer; a second intermetallic compound layer containing a CuSn-based intermetallic compound; a Cu layer; and a third intermetallic compound layer containing a CuSn-based intermetallic compound, and the above layers are sequentially arranged from the electrode of the substrate toward the electrode of the semiconductor element to configure the mounted layers.
