Semiconductor device structure and method for preparing the same |
| abstract |
The present application discloses a semiconductor device structure and a method for preparing the same. The method includes forming a ring structure over a substrate; performing an etching process to form an annular semiconductor fin under the ring structure; forming a lower source/drain region on the surface of the substrate in contact with a bottom portion of the annular semiconductor fin; forming an inner gate structure in contact with an inner sidewall of the annular semiconductor fin and forming an outer gate structure in contact with an outer sidewall of the annular semiconductor fin; and forming an upper source/drain region on an upper portion of the annular semiconductor fin. |
