  • As the demand for high frequency(bandwidth) optical module is increased, there is a need for fabricating silicon optical bench(SiOB) with low parasitic impedance. In this paper, we discuss multi-layer structure method for manufacturing SiOB with low capacitance. This structure method decreases the capacitance between the conductive patterns for about 94∼97% compared to the conventional structure without raising the resistivity of silicon, or increasing the thickness of the dielectric film.
