    摘要: A tungsten or other metal layer is chemical vapor deposited using a source gas containing tungsten, a reducing gas and a nitrogen-containing gas. The nitrogen-containing gas can act as a surface roughness reducing gas that reduces the roughness of the tungsten layer compared to a tungsten layer that is chemical vapor deposited using the source gas containing tungsten and the reducing gas, but without using the surface roughness reducing gas. Viewed in another way, the nitrogen-containing gas acts as a growth rate controlling gas that produces uniform growth of the tungsten layer in a plurality of directions compared to a tungsten layer that is deposited using the source gas containing tungsten and the reducing gas, but without using the growth rate controlling gas.

    摘要: A method for forming a light guide layer with improved transmission reliability in a semiconductor substrate, the method including forming a trench in the semiconductor substrate, forming a cladding layer and a preliminary light guide layer in the trench such that only one of opposite side end portions of the preliminary light guide layer is in contact with an inner sidewall of the trench, and performing a thermal treatment on the substrate to change the preliminary light guide layer into the light guide layer.

    摘要: A contact structure includes a lower conductive pattern disposed on a predetermined region of a semiconductor substrate. The lower conductive layer has a concave region at a predetermined region of a top surface thereof. An embedding conductive layer fills the concave region. The top surface of the embedding conductive layer is placed at least as high as the height of the flat top surface of the lower conductive pattern. A mold layer is disposed to cover the semiconductor substrate, the lower conductive pattern and the embedding conductive layer. An upper conductive pattern is arranged in an intaglio pattern. The intaglio pattern is disposed in the mold layer to expose a predetermined region of the embedding conductive layer.
