Abstract
A three dimensional semiconductor device includes first, second, third and fourth source/drain patterns sequentially stacked on a substrate, a contact structure on the first to fourth source/drain patterns and a contact line on the contact structure. The contact structure includes a first active contact on the first source/drain pattern, a second active contact on the second source/drain pattern, a third active contact on the third source/drain pattern, and a fourth active contact on the fourth source/drain pattern. A first vertical extension part of the first active contact is adjacent to one side of the contact structure, and a second vertical extension part of the second active contact is adjacent to the other side of the contact structure. A third vertical extension part of the third active contact is disposed between the first and second vertical extension parts and is closer to the first vertical extension part.
