Abstract

An active region includes a body region in which first and second transistors are formed, a connection portion to which a potential of the body region is connected, and a lead portion that connects the body region and the connection portion. Source regions or drain regions of the first and second transistors formed in the body region are provided in a common region. Each of the lead portions extends from a corresponding channel region such that the lead portions are isolated from each other, and a gate electrode extends thereon. A width of the lead portion is narrower than a distance between corresponding ones of contact portions of the source regions and the drain regions of the first and second transistors. A width of the connection portion is equal to or narrower than a gate width of the gate electrode extending on the lead portion.
