Abstract:
1. A semiconductor device comprising: a base substrate; a semiconductor chip mounted on the base substrate; a dielectric substrate mounted on the base substrate; a circuit pattern mounted on the dielectric substrate and connected with the semiconductor chip through a conductor line; a dielectric block mounted on the base substrate; a waveguide mounted on the dielectric block, the waveguide having a lead connection portion connected with a lead wire and a wire connection portion connected with the circuit pattern; a protection pattern made of a conductor and having a first surface formed on the dielectric block at a position spaced from the waveguide; a metal plating layer formed on a side face of the dielectric block and formed on the protection pattern to extend over at least a portion of a second surface of the protection pattern opposite to the first surface formed on the dielectric block; and a length of the wire connection portion in a direction that is perpendicular to a direction in which a signal propagates in the waveguide is longer than that of the lead connection portion.
