The cap and the mounting substrate forming the cavity are made of, for example, ceramics. These ceramics are made of a material having a thermal expansion coefficient close to that of the semiconductor pellet. On the other hand, the back surface of the semiconductor pellet is fixed to the inner surface of the cap with solder for sealing. The sealing solder is made of the same material as the sealing solder that fixes the mounting substrate and the cap. Here, the thermal expansion coefficient of the cavity is determined by the thermal expansion coefficient of each of the cap and the sealing solder that fixes the cap and the mounting substrate. On the other hand, the total thermal expansion coefficient of the component parts is determined by the thermal expansion coefficient of each of the sealing solder for fixing the semiconductor pellet and the cap, the semiconductor pellet, and the bump electrode. Therefore, the coefficient of thermal expansion of the cavity and the total coefficient of thermal expansion of the components are different. Therefore, for example, the physical distance fluctuation (fine displacement) caused by the difference in the coefficient of thermal expansion during the temperature cycle is
It is generated between the mounting substrate and the semiconductor pellet. Since the stress caused by the generated minute displacement concentrates on the bump electrode portion, there is a problem that the reliability of the bump electrode is lowered.
