Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC H

Claim 0:
1. A semiconductor device, comprising:
an active pattern on a substrate;
a source/drain pattern on the active pattern, the source/drain pattern including a bottom surface in contact with a top surface of the active pattern;
a channel pattern connected to the source/drain pattern;
a gate electrode extended to cross the channel pattern;
a fence insulating layer extended from a side surface of the active pattern to a lower side surface of the source/drain pattern; and
a pair of middle insulating patterns at both sides of the bottom surface of the source/drain pattern, the pair of middle insulating patterns being between the active pattern and the source/drain pattern in contact with an inner side surface of the fence insulating layer.
