Abstract
The accuracy in forming a gate electrode or an interconnect is improved by using a dummy gate electrode or a dummy interconnect. In addition, the dummy gate electrode or the dummy interconnect is removed, so that a region where the dummy gate electrode or the dummy interconnect has been disposed can be used as a region for forming another composing element.
