    摘要: Integrated circuit devices have a first substrate layer and a first transistor on the first substrate layer. A first interlayer insulating film covers the first transistor. A second substrate layer is on the first interlayer insulating film and a second transistor is on the second substrate layer. A second interlayer insulating film covers the second transistor. A contact extends through the second interlayer insulating film, the second substrate layer and the first interlayer insulating film. The contact includes a lower contact and an upper contact that contacts an upper surface of the lower contact to define an interface therebetween. The interface is located at a height no greater than a height of a top surface of the second substrate and greater than a height of a bottom surface of the second substrate layer.

    摘要: First, second and third layers are formed on a substrate for forming a fine pattern. A first mask pattern having a first space is formed on the third layer. A third layer pattern having a second space exposing the second layer is formed. A first sacrificial layer is formed on the second layer having the third layer pattern. A fourth layer is formed on the first sacrificial layer. A double mask pattern including the first and second mask patterns is formed using the second mask pattern in the second space. A second sacrificial layer is formed on the first sacrificial layer. A sacrificial layer pattern having a third space is formed by removing the double mask pattern, the third layer pattern, and a portion of the first sacrificial layer. An insulation layer pattern is formed by removing a portion of the first and second layers.
