ABSTRACT:
An upper sealing ring and a lower sealing ring are adhered by sealing solder. The width of tip end of sealing projection is narrower than the width of the lower sealing ring. Therefore, the sealing solder is placed on lower sealing ring and on the side surface of upper sealing ring. Further, an upper connection pad and a lower connection pad are adhered by connecting solder. The width of a tip end of a connection projection is narrower than the width of lower connection pad. Therefore, the connecting solder is placed on the lower connection pad and on the side surface of upper connection pad. Thus, a package is provided, which attains satisfactory electrical connection and hermetic seal after solder joint of the upper and lower substrates.
