Abstract
A semiconductor integrated circuit such as a semi-custom LSI includes a semiconductor substrate, a plurality of circuit elements formed on the semiconductor substrate and aligned in a plural number of lines, selected one's of the circuit elements being used in an electrical circuit formed in the semiconductor integrated circuit, unselected one's of the circuit elements being left without used in the electrical circuit, at least one set of capacitor cells formed on but isolated from the unselected one of the circuit element, wirings formed in spaces between the lines of the circuit elements to interconnect the selected ones of the circuit elements, and a means for connecting at least one of the capacitor cells selected in the one set to one of wirings.
