Abstract

A semiconductor device includes a device isolation layer defining a cell active area in a substrate. A plurality of buried contacts is electrically connected with the substrate and arranged in a first direction. A bit line structure extends in a second direction between adjacent buried contacts of the plurality of buried contacts. The bit line structure includes a bit line pass portion and a bit line contact portion. The bit line structure is electrically connected with the cell active area. A first buffer pattern is disposed between the substrate and the bit line pass portion. The first buffer pattern has a T-shape in a cross-section taken along the first direction.
