Abstract
Semiconductor equipment includes a semiconductor substrate, a plurality of transistors having a source cell and a drain cell disposed alternately on the substrate, and upper and lower layer wirings for electrically connecting the source cells and the drain cells. The lower layer wiring includes a first source wiring for connecting the neighboring source cells and a first drain wiring for connecting the neighboring drain cells. The upper layer wiring includes a second source wiring for connecting to the first source wiring and a second drain wiring for connecting to the first drain wiring. A width of the second source wiring is wider than that of the first source wiring, and a width of the second drain wiring is wider than that of the first drain wiring. The second source wiring and the second drain wiring are disposed alternately.
