Abstract:
Semiconductor device packages and methods of manufacturing the semiconductor device packages are provided. A semiconductor device package may include a bonding layer between a substrate and a semiconductor chip, and the bonding layer may include an intermetallic compound. The intermetallic compound may be a compound of metal and solder material. The intermetallic compound may include Ag3Sn. A method of manufacturing the semiconductor device package may include forming a bonding layer, which bonds a semiconductor chip to a substrate, by using a mixed paste including metal particles and a solder material. The bonding layer may be formed by forming an intermetallic compound, which is formed by heating the mixed paste to react the metal particles with the solder material.
Abstract:
According to example embodiments of inventive concepts, a power device includes a semiconductor structure having a first surface facing a second surface, an upper electrode, and a lower electrode. The upper electrode may include a first contact layer that is on the first surface of the semiconductor structure, and a first bonding pad layer that is on the first contact layer and is formed of a metal containing nickel (Ni). The lower electrode may include a second contact layer that is under the second surface of the semiconductor structure, and a second bonding pad layer that is under the second contact layer and is formed of a metal containing Ni.
