Abstract: Disclosed are semiconductor apparatuses and methods of fabricating the same. According to the methods, the number of operations for fabricating the semiconductor apparatuses having a plurality of layers may be the same as the number of operations for fabricating a semiconductor apparatus having one layer. The semiconductor apparatuses may include first active regions extending in the same direction, in parallel, separated from each other and including first and second impurity doped regions on opposite ends of the first active regions from each other. The semiconductor apparatuses may further include second active regions on a layer above the first active regions, extending in the same direction as the first active regions, separated from each other, in parallel, and including first and second impurity doped regions on opposite ends of the second active regions from each other.
