Only high-frequency current flows between them, not DC current or signal current of relatively low frequency.

Note that the surge impedance Zs of the switching element 19 is unknown.

- a line element is formed on a semiconductor chip, a lead, or a kasumihara wiring on a printed circuit board, and a characteristic impedance of the line element in a high frequency region is set to an optimum value by increasing a capacitance per unit length. By doing so, the decoupling performance is given to the grape wiring including the line element.
- the line element is composed of, for example, a substrate (conductor such as polysilicon or metal) having a ground potential and a power supply. It is formed by arranging a wiring through which a current flows in a different layer with an insulating film interposed therebetween.
- a method for increasing the capacitance per unit length of such a line element is as follows.
- the effective line length of the line element 17 is set to be longer than 1/4 a // f, which is the wavelength of the lowest frequency (hereinafter, referred to as the lowest decoupling frequency) in the frequency range to be decoupled.
- the characteristic I 1 raw impedance of the line element 17 can be represented by ⁇ (L / C) regardless of the frequency in the frequency range to be decoupled.
- ⁇ is the wavelength of the lowest frequency
- ⁇ is the relative permittivity of the insulating film
- L is the inductance per unit length of the line element 17
- C is the capacitance per unit length of the line element 17.
- the line element 17 is formed in an uneven shape while maintaining a constant distance between the ground wiring and the temporary wiring, or by forming an uneven portion on the surface of the line element, thereby arranging the line layout area.
- the wiring width and wiring length are increased without increasing the wiring width.
- the line element is mounted on a semiconductor chip.
- the line element has a capacitance characteristic even at the highest frequency among the high-frequency signals generated by the switching element on the semiconductor chip.
- the line element is mounted on the lead of the semiconductor device.

- the semiconductor circuit according to the present invention includes a plurality of line elements having different effective bands in order to realize a wider frequency band required for decoupling performance and a higher density of the semiconductor device. Or, it is distributed and mounted at multiple locations such as a printed circuit board. At this time, it is preferable to set the characteristic impedance of each line element so that the fluctuation of the DC power supply is 5% or less.
- the insulating film In order to prevent the incident wave to the line element from leaking out, the insulating film must have some loss.
- the dielectric loss of the insulating film is preferably large enough to consume electromagnetic waves incident on the line element.
- a decoupling circuit having better decoupling performance up to a high frequency region than before can be obtained.
- Generation of high-frequency noise propagating to the DC power supply is suppressed, electromagnetic interference is reduced, and signal waveform distortion due to high-frequency noise generated in the switching element is reduced.
- FIG. 4 is a rough graph showing the relationship between the characteristic impedance of the line element and the value of the element S 21 of the scattering matrix [S].
- FIG. 4 shows an example in which the characteristic impedance Z 0 of the power supply wiring is 50 ⁇ and 200 ⁇ , respectively.
- the value of the characteristic impedance Z O of the power supply wiring varies depending on whether it is formed on a printed circuit board or a chip of a semiconductor device, but is set to about 50 ⁇ to about 200 ⁇ .
- the value of S21 is required to be 140 dB or less as a decoupling performance.
