A method of fabricating a semiconductor device having a recess region in an insulation layer on a silicon substrate, comprising the steps of depositing a barrier metal over the entire surface of the insulation layer including the substrate surface in the recess region, depositing selectively an anti-nucleation layer on the barrier metal except in the recess region, depositing a CVD-Al layer on the barrier metal in the recess region, depositing a metal or a metal alloy inhibiting aluminum migration on the anti-nucleation layer and the barrier metal except in the recess region, and depositing a PVD-Al layer and re-flowing the PVD-Al layer, for improving the quality of aluminum grooves. The present method inhibits PVD-Al migration and grain growth, which results in preventing abnormal patterning in the semiconductor device.

A semiconductor device fabrication method having a recess region in an insulation layer on a silicon substrate, includes the steps of depositing a barrier metal on an entire surface of the insulation layer, filling the recess region with an oxide layer, removing the barrier metal on an upper side of the insulation layer, removing the oxide layer in the recess region and exposing the barrier metal of the recess region, depositing a CVD-Al layer on the barrier metal, and depositing a PVD-Al layer on the CVD-Al layer and re-flowing the PVD-Al layer. The fabrication method of a semiconductor integrated circuit according to the present invention selectively removes a barrier metal in the outside of the recess region to expose the insulation layer to the air, and deposits the CVD-Al layer and the PVD-Al layer, which results in controlling abnormal growth of the CVD-Al metal.

A fuse base insulating region, for example, an insulating interlayer or a compensation region disposed in an insulating interlayer, is formed on a substrate. An etch stop layer is formed on the fuse base insulating region and forming an insulating interlayer having a lower dielectric constant than the first fuse base insulating region on the etch stop layer. A trench extending through the insulating interlayer and the etch stop layer and at least partially into the fuse base insulating region is formed. A fuse is formed in the trench. The fuse base insulating region may have a greater mechanical strength and/or density than the second insulating interlayer.

In a method of manufacturing a metal wiring structure, a first metal wiring and a first barrier layer are formed on a substrate, and the first barrier layer is nitridated. An insulating interlayer is formed on the substrate so as to extend over the first metal wiring and the first barrier layer. Part of the insulating interlayer is removed to form a hole exposing at least part of the first metal wiring and part of the first barrier layer. A nitridation plasma treatment is performed on the exposed portion of the first barrier layer. A second barrier layer is formed along the bottom and sides of the hole. A plug is formed on the second barrier layer to fill the hole.

A semiconductor device can include an insulation layer on that is on a substrate on which a plurality of lower conductive structures are formed, where the insulation layer has an opening. A barrier layer is on a sidewall and a bottom of the opening of the insulation layer, where the barrier layer includes a first barrier layer in which a constituent of a first deoxidizing material is richer than a metal material in the first barrier layer and a second barrier layer in which a metal material in the second barrier layer is richer than a constituent of a second deoxidizing material. An interconnection is in the opening of which the sidewall and the bottom are covered with the barrier layer, the interconnection is electrically connected to the lower conductive structure.

摘要:
In a method for forming a wiring of a semiconductor device using an atomic layer deposition, an insulating interlayer is formed on a substrate. Tantalum amine derivatives represented by a chemical formula Ta(NR1)(NR2R3)3 in which R1, R2 and R3 represent H or C1-C6 alkyl group are introduced onto the insulating interlayer. A portion of the tantalum amine derivatives is chemisorbed on the insulating interlayer. The rest of tantalum amine derivatives non-chemisorbed on the insulating interlayer is removed from the insulating interlayer. A reacting gas is introduced onto the insulating interlayer. A ligand in the tantalum amine derivatives chemisorbed on the insulating interlayer is removed from the tantalum amine derivatives by a chemical reaction between the reacting gas and the ligand to form a solid material including tantalum nitride. The solid material is accumulated on the insulating interlayer through repeating the above processes to form a wiring.
