A semiconductor device with under bump metallurgy and a method for fabricating the semiconductor device are provided, wherein a passivation layer is deposited on a surface of the semiconductor device where a plurality of bond pads are disposed, and formed with a plurality of openings for exposing the bond pads. Further, for a one wave optical amplifier, an optical amplifying medium capable of causing a pair induced quenching phenomenon is applied to the optical amplifying means on the signal light input side, so that the optical surge is suppressed utilizing the degradation of output power efficiency by the PIQ caused at the time when the input power is increased. The organ container may be a portable organ preservation device or a portable organ perfusion apparatus. carbon atoms; m is an integer of 1\u02dc10; q is a number satisfying a relation of 0<q\u2266r+2;Component : phosphoric acid ester compound represented by the following general formula.
