Abstract(in Japanese) (See Japanese page)
Abstract(in English) The hydrogen (H) or helium (He) ion irradiation on a silicon (Si) substrate had been proposed to reduce loss in high frequency electromagnetic fields. It was confirmed by measurement that the Q factor of on-chip spiral inductor can increase and gain of on-chip antenna can reduce because the conductivity of silicon substrate decreases by ion irradiation. Although the change of the conductivity of Si by ion irradiation was investigated, the change of dielectric constant has not been investigated. The change of dielectric constant of Si by ion irradiation was measured by terahertz time-domain spectroscopy system in this paper. The measured dielectric constant of Si was changed from 11.80 (before ion irradiation) to 11.34 after ion irradiation. The measured frequency characteristic of reflection coefficient with measured dielectric constant in the simulation agrees well with measured one.
