Low-Microwave Loss Coplanar Waveguides Fabricated on High-Resistivity Silicon Substrate
-
Abstract
Three kinds of coplanar waveguides (CPWs) are designed and fabricated on different silicon substrates--common low-resistivity silicon substrate (LRS),LRS with a 3μm-thick silicon oxide interlayer, and high-resistivity silicon (HRS) substrate.The results show that the microwave loss of a CPW on LRS is too high to be used, but it can be greatly reduced by adding a thick interlayer of silicon oxide between the CPW transmission lines and the LRS.A CPW directly on HRS shows a loss lower than 2dB/cm in the range of 0~26GHz and the process is simple,so HRS is a more suitable CPW substrate. -
