2. Description of the Related Art Today, semiconductor devices are becoming faster and higher in frequency.
Highly integrated technology has advanced remarkably. Microwave,
Even in the millimeter wave band, circuits that have been conventionally composed of individual elements have been integrated, and downsizing and low power consumption of the device have been realized. In addition, the importance of signal transmission paths between elements is increasing with the speeding up of elements. Conventionally, as a method for transmitting a high-speed signal on a semiconductor surface, a microstrip line and a coplanar line which are widely used for a signal transmission line of an analog high-speed element are used. A typical microstrip line is shown in FIG. Reference numeral 41 is an insulator having a high dielectric constant and serves as a semiconductor substrate in a semiconductor element. 42 is a strip conductor and 43 is a ground conductor.
The microstrip line is a modification of the parallel plate waveguide, and applies an electric field between the ground conductor 43 and the strip conductor 42 to propagate electromagnetic waves. The dotted line simply shows the electromagnetic field generated at this time.

However, in the microstrip line shown in FIG. 4, a connection process from the back surface such as a via hole is required to ground the semiconductor element formed on the surface, and the size of the via hole is large. Due to this limitation, integration is difficult. Further, since the signal lines have to be widened in order to reduce the interference between the signals, the proportion occupied by the transmission line becomes large, which is unsuitable for the integration of semiconductor elements.
