Abstract:
A semiconductor device comprising:a signal line, which is capable of passing a signal having a desired frequency f0 therethrough, formed on a semiconductor substrate; and a differential signal line through which a signal in opposite phase to said signal passes, or which is connected to a ground power supply, said signal line and said differential signal line being laminated via an insulating layer so as to be substantially in parallel with each other, and an actual wiring length l of said signal line being longer than a wiring length l0 determined by the following equation l0=LC+R2+8&it;Ï€2&it;f02&it;L24&it;Ï€2&it;f02&it;C2R2+4&it;Ï€2&it;f02&it;L2where R represents a resistance component, L represents an inductance component, and C represent a capacitance component per unit length of said signal line in such a case that said differential signal line does not exist.
