Abstract
An electric signal transmission line includes a signal electrode portion, a ground electrode portion and a dielectric portion formed on a semiconductor substrate. The signal electrode portion has a metal electrode through which an electric signals flows. The ground electrode portion has a grounded metal electrode. The metal electrode of the signal electrode portion and the metal electrode of the ground electrode portion are connected with a semiconductor PN junction. The dielectric portion is formed by using a dielectric to cover a region between the metal electrode of the signal electrode portion and the metal electrode of the ground electrode portion through which a line of electric force runs and is a region in which energy of transmitted electric signals exist.
