Semiconductor device including via plug and method of forming the same |
| abstract |
A semiconductor device includes a lower insulating layer disposed on a substrate. A conductive pattern is formed in the lower insulating layer. A middle insulating layer is disposed on the lower insulating layer and the conductive pattern. A via control region is formed in the middle insulating layer. An upper insulating layer is disposed on the middle insulating layer and the via control region. A via plug is formed to pass through the via control region and to be connected to the conductive pattern. The via control region has a lower etch rate than the middle insulating layer. |
