A semiconductor device in which input terminals for external interrupts can be set as desired. A plurality of external input terminals can be specified as interrupt terminals which output an input signal to an external interrupt circuit via an interrupt terminal selector. A selection control circuit specifies whether a plurality of external input terminals are used as interrupt terminals. According to the selection control circuit, the interrupt terminal selector outputs to the external interrupt circuit an input signal entered from an external input terminal which is specified as an interrupt terminal out of the plurality of external input terminals.

The composite dielectric of the present invention contains an aromatic liquid crystal polyester and a dielectric ceramic powder arranged in the aromatic liquid crystal polyester, wherein the dielectric ceramic powder exhibits a Q value greater than 650 at a frequency of 1 GHz by perturbation. A wiring board comprising a composite dielectric sheet made of a composite dielectric having such a characteristic exhibits a high dielectric constant and a low dielectric dissipation factor, thereby yielding less transmission loss, and thus can favorably be used in electronic instruments driven in high-frequency regions.

Provided is a method for manufacturing a multilayer wiring board, whereby even if the multilayer wiring board suffers warping or irregularities, thin-film patterns with great uniformity that are to be used as a mask for forming a wiring layer can be obtained in a simple way. A primer-coated metal foil 20 composed of a primer resin layer 21 and a metal layer 22 is placed on a surface of a double-face CCL 10, which is prepared by applying metal layers 12 and 13 onto the surfaces of a support base 11, and the primer-coated metal foil 20 and the double-face CCL 10 are bonded and the primer resin layer 21 is cured. A via Vb is thereafter formed from the metal layer 22 side, and a metal-plate layer 30 is formed on the resulting metal layer 22. After that, the etched down metal-plate layer 30 and the metal layer 22 are patterned, and using the patterned layers as a mask, the primer resin layer 21 is patterned. Using the patterned primer resin layer 21 as a mask, the metal layer 12 of the double-face CCL 10 and the metal-plate layer 30 are patterned to form a wiring pattern.
