<P>PROBLEM TO BE SOLVED: To provide such a structure that can prevent a leakage among wires through a carbon containing in a sealing resin, and provide a structure of an electromagnetic shield that can prevent discharging and entry of electromagnetic waves from a semiconductor device or a wire and to the outside. <P>SOLUTION: A dummy wire 10 is provided outside so as to cover a wire 3 entirely at a narrower pitch and much more than the wire 3. Due to such a structure, even if carbon particles exist, the carbon particles larger in size than an interval between the dummy wires 10 is impossible to enter the inside, generating no leakage between the wires 3. In addition, the carbon particles smaller in size than an interval between the dummy wires 10 are possible to enter the inside, however, they are smaller than an interval between the wires 3, resulting in no leakage between the wires 3. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
