Abstract
A plurality of diffused resistors and a plurality of wirings (resistive elements) are alternately disposed along a virtual line, and those diffused resistors and wirings are connected in series by contact vias. In the same wiring layer as that of the wirings, a dummy pattern is formed so as to surround a formation region of the wirings and the diffused resistors. A space between the dummy pattern and the wirings is set in accordance with, for example, a minimum space between wirings in a chip formation portion.
