Semiconductor device and manufacturing method thereof |
| abstract |
A semiconductor device is provided. The semiconductor device includes a core structure, a first pattern and a second pattern. The core structure is disposed on a substrate. The first pattern covers a sidewall of a bottom portion of the core structure. The top surface of the first pattern is lower than a top surface of the core structure. The second pattern is disposed on the first pattern and covering a top portion of the core structure. A sidewall of the top portion of the core structure and the top surface of the core structure are covered by the second pattern. The second pattern has an upper portion tapered away from the substrate. A material of the first pattern is different from a material of the second pattern. |
