Abstract
A semiconductor device includes first, second and third semiconductor regions, each surrounded by an element isolation layer, first and second transistors of the first semiconductor region connected in parallel between first and second nodes, a third transistor of the second semiconductor region between the second node and the first transistor, and a fourth transistor of the third semiconductor region between the second node and the second transistor. Gates of the first and second transistors extend in a first direction and are spaced from each other in a second direction. A first distance which is equal to a longer of two distances between the element isolation layer and the gate electrode of the first transistor in the second direction, is greater than a second distance which is equal to a longer of two distances between the element isolation layer and the gate electrode of the third transistor in the second direction.
