Abstract
Semiconductor devices are provided. A semiconductor device includes a bit line structure and a contact plug. The contact plug is adjacent a sidewall of the bit line structure and is on a sloped surface of the bit line structure. Moreover, in some embodiments, a level of the sloped surface of the bit line structure becomes lower as the sloped surface approaches the sidewall of the bit line structure.
