摘要： On a surface of a Si substrate, a nonvolatile memory cell, an nMOS transistor, and a pMOS transistor are formed, and thereafter an interlayer insulation film covering the nonvolatile memory cell, the nMOS transistor, and the pMOS transistor is formed. Next, in the interlayer insulation film, there are formed plural contact plugs connected respectively to a control gate of the nonvolatile memory cell, a source or a drain of the nMOS transistor, and a source or a drain of the pMOS transistor. Thereafter, there is formed a single-layer wiring connecting the control gate to the sources or drains of the nMOS transistor and the pMOS transistor via the plural contact plugs.

摘要： An object of the present invention is to realize almost the same transmission characteristic in all wavelengths at a transmission rate of 10 Gb/s or more. An optical transmitter 10 outputs WDM signal light multiplexed with signal light of a plurality of wavelengths toward an optical transmission line 12. The optical transmission line 12 comprises an optical transmission fiber 14, an optical repeating amplifier 16 and a dispersion compensating fiber 18. The gain characteristic of the optical repeating amplifier 16 is set so that the gain becomes the maximum at the effective zero dispersion wavelength of the optical transmission line 12 and that lowers inversely proportional to the distance from the effective zero dispersion wavelength. The whole optical transmission line 12 is set so that the peak power deviation between the effective zero dispersion wavelength &lgr;0 and the wavelength &lgr;1 or &lgr;n on both end becomes approximately 4 dB.
