摘要:
The present invention relates to semiconductor devices and a method of fabricating the same. According to a method of manufacturing semiconductor devices, there is first provided a semiconductor substrate in which a first pre-metal dielectric layer including trenches is formed. A diffusion barrier layer is formed on the entire surface including the trenches. A metal layer is formed on the diffusion barrier layer including the trenches, thereby gap-filling the trenches. A polish etching process is performed on the metal layer and the diffusion barrier layer so that the diffusion barrier layer and the metal layer remain within the trenches. An etching process of lowering a height of the metal layer is performed in order to increase a distance between metal lines. A capping layer is formed on the entire surface including exposed sidewalls of the first pre-metal dielectric layer. A second pre-metal dielectric layer is formed over the capping layer.

摘要:
A first conductive layer is formed over a substrate in which contact holes are formed in an interlayer insulating layer. The first conductive layer is melted by an annealing process, thus coating the lower sidewalls of the contact holes and partially filling the contact holes. A second conductive layer is deposited with a method having selectivity with respect to the same material as the first conductive layer, thus fully filling the contact holes. A metal line is formed on the second conductive layer. The contact holes are completely filled with a conductive material and the load of a CMP process can be alleviated. Accordingly, the electrical characteristics of a device can be improved, process reliability can be improved, and process repeatablity can be improved.

A method of forming a metal wire in a semiconductor device includes performing a first etching process on an insulating layer formed on a semiconductor substrate to form a trench and an insulating layer pattern, the insulating layer pattern defining the trench. A barrier metal layer is formed over the insulating layer pattern and the trench. A second etching process is performed on the barrier metal layer to expose upper corners of the trench while leaving the trench substantially covered with the barrier metal layer. A metal layer is formed over the barrier metal layer in the trench. A heat treatment process is performed for reflowing the metal layer. The metal layer is planarized.
