摘要:
A gate structure is formed on a substrate. An insulating interlayer is formed covering the gate structure. The substrate is heat treated while exposing a surface of the insulating interlayer to a hydrogen gas atmosphere. A silicon nitride layer is formed directly on the interlayer insulating layer after the heat treatment and a metal wiring is formed on the insulating interlayer. The metal wiring may include copper. Heat treating the substrate while exposing a surface of the interlayer insulating layer to a hydrogen gas atmosphere may be preceded by forming a plug through the first insulating interlayer that contacts the substrate, and the metal wiring may be electrically connected to the plug. The plug may include tungsten.

A bonding pad structure for a semiconductor device includes a first lower metal layer beneath a second upper metal layer in a bonding region of the device. The lower metal layer is formed such that the metal of the lower metal layer is absent from the bonding region. As a result, if damage occurs to the structure during procedures such as probing or bonding at the bonding region, the lower metal is not exposed to the environment. Oxidation of the lower metal layer by exposure to the environment is prevented, thus improving reliability of the device.

A structure and formation method for electrically connecting aluminum and copper interconnections stabilize a semiconductor metallization process using an inner shape electrically connecting the aluminum and copper interconnections. To this end, a copper interconnection is disposed on a semiconductor substrate. An interconnection induction layer and an interconnection insertion layer are sequentially formed on the copper interconnection to have a contact hole exposing the copper interconnection. An upper diameter of the contact hole may be formed to be larger than a lower diameter thereof. A barrier layer and an aluminum interconnection are filled in the contact hole. The aluminum interconnection is formed not to directly contact the copper interconnection through the contact hole.

A semiconductor device includes a first interlayer dielectric including a trench on a semiconductor layer, a mask pattern on the first interlayer dielectric, a first conductive pattern in the trench, and a second interlayer dielectric on the mask pattern. The second interlayer dielectric includes an opening over the first conductive pattern. A second conductive pattern is in the opening and is electrically connected to the first conductive pattern.
