Abstract
A semiconductor device and a method of manufacturing the same are provided which are novel and fully improved and are capable of lowering satisfactorily a high-frequency resistance or direct current resistance in a signal line. The semiconductor device is composed of a semiconductor substrate on which predetermined circuit devices are mounted, an insulating film formed on the substrate in a manner that it covers the circuit devices and a conductive path formed on the insulating film to electrically connect the circuit devices. A concave trench is formed in a predetermined position on the semiconductor substrate and the conductive path is formed at a bottom of the concave trench in a manner that it extends along the concave trench, with interlayer dielectrics interposed between conductive layers constituting the conductive path.
