SEMICONDUCTOR DEVICE INCLUDING A PAIR OF SHIELD LINES

摘要

A semiconductor device includes a first circuit, a second circuit, a first wire, and a pair of shield lines. The first circuit includes a voltage generating circuit generating a predetermined voltage and produces the predetermined voltage at an output end thereof. The first wire connects the output end of the first circuit to an input end of the second circuit. The pair of shield lines is disposed so as to sandwich the first wire therebetween. One of the shield lines is supplied with a power supply potential for driving at least one of the voltage generating circuit and the second circuit. Another of the shield lines is supplied with a ground potential for driving at least one of the voltage generating circuit and the second circuit.
