摘要:
A method of forming a pattern includes forming an etch target layer on a substrate, forming sacrificial patterns on the etch target layer, the sacrificial patterns including a carbon-containing material, providing a silicon-sulfur compound or a sulfur-containing gas onto the sacrificial patterns to form a seed layer, providing a silicon precursor onto the seed layer to form silicon-containing mask patterns, and at least partially etching the etch target layer using the mask patterns.

A semiconductor device includes a lower interconnection having second conductivity-type impurities on a substrate having first conductivity-type impurities. A switching device is on the lower interconnection. A first blocking layer is provided between the lower interconnection and the switching device. The first blocking layer includes carbon (C), germanium (Ge), or a combination thereof. A second blocking layer may be provided between the substrate and the lower interconnection.

摘要:
Semiconductor devices, and methods of manufacturing the same, include a field region in a semiconductor substrate to define an active region. An interlayer insulating layer is on the semiconductor substrate. A semiconductor pattern is within a hole vertically extending through the interlayer insulating layer. The semiconductor pattern is in contact with the active region. A barrier region is between the semiconductor pattern and the interlayer insulating layer. The barrier region includes a first buffer dielectric material and a barrier dielectric material. The first buffer dielectric material is between the barrier dielectric material and the semiconductor pattern, and the barrier dielectric material is spaced apart from both the semiconductor pattern and the active region.
