    摘要: A method of manufacturing a semiconductor device, which comprises the steps of forming an intermediate layer on an insulating layer, forming a groove in the intermediate layer and the insulating layer, forming a first barrier layer on the intermediate layer, depositing a wiring layer on the first barrier layer to thereby fill the groove with the wiring layer, performing a flattening treatment of the wiring layer, removing a surface portion of the wiring to thereby permit the surface of the wiring to be recessed lower than a surface of the insulating layer, thus forming a recessed portion, forming a second barrier layer on the intermediate layer and on an inner wall of the recessed portion, performing a flattening treatment of the second barrier layer, thereby, and selectively removing the intermediate layer, exposing the insulating layer.

    摘要: A groove or hole is formed in an insulating layer formed on a semiconductor substrate, and a first conductive layer including a first metal element is formed on a surface of the insulating layer. By oxidizing the first conductive layer, an oxide layer of the first metal element is formed on a surface of the first conductive layer. A second conductive layer including a second metal element having a free energy of oxide formation lower than that of the first metal element is deposited thereon. By reducing the oxide layer of the first metal element by the second metal element, an oxide layer of the second metal element is formed at the interface between the first conductive layer and the second conductive layer. Further, an interconnection is buried in the groove or hole of the insulating layer. Thereby, a thin second metal oxide layer having excellent barrier properties against an interconnection material and excellent adhesion to the interconnection material can be selectively formed with a uniform thickness on the surface of the first conductive layer used as a barrier metal layer of the interconnection.
