Claim 17:
18. A semiconductor device comprising:
a substrate;
a first semiconductor pattern on the substrate and extending in a first direction that is parallel to a top surface of the substrate, the first semiconductor pattern including a first end, a second end opposite the first end, and a first channel region between the first end and the second end;
a second semiconductor pattern extending in the first direction and spaced apart from the first semiconductor pattern in a second direction that is parallel to the top surface of the substrate and is perpendicular to the first direction, the second semiconductor pattern including a third end, a fourth end opposite the third end, and a second channel region between the third end and the fourth end;
an insulating layer on the substrate and between the first semiconductor pattern and the second semiconductor pattern;
a bit line extending in the second direction and connected to the first end of the first semiconductor pattern and the third end of the second semiconductor pattern;
a first capacitor lower electrode extending in the first direction and connected to the second end of the first semiconductor pattern;
a second capacitor lower electrode extending in the first direction and connected to the fourth end of the second semiconductor pattern;
a first gate electrode adjacent to the first channel region of the first semiconductor pattern;
a second gate electrode adjacent to the second channel region of the second semiconductor pattern; and
a hole extending through the first semiconductor pattern in a third direction that is perpendicular to the top surface of the substrate,
wherein the first gate electrode includes:
a first portion on a bottom surface of the first semiconductor pattern;
a second portion on a top surface of the first semiconductor pattern; and
a third portion in the hole, and
wherein the third portion of the first gate electrode contacts the first portion and the second portion of the first gate electrode.
