Semiconductor device including fin structure with two channel layers and manufacturing method thereof |
摘要 |
A semiconductor device includes a fin structure protruding from a substrate and having a top face and a first side face and a second side face opposite to the first side face, and first semiconductor layers disposed over the first and second side faces of the fin structure. A thickness in a vertical direction of the first semiconductor layers is smaller than a height of the fin structure. |

1. A semiconductor device, comprising:
a fin structure protruding from a substrate in a vertical direction and having a top face and a first side face and a second side face opposite to the first side face; first semiconductor layers disposed over the first and second side faces of the fin structure; a gate electrode covering the top fade and the first and second side faces of the fin structure and covering the first semiconductor layers; and an insulating layer interposed between the gate electrode and the fin structure and between the gate electrode and the first semiconductor layers, wherein a thickness in the vertical direction of the first semiconductor layers is smaller than a height of the fin structure. |
