    Abstract: A trench is formed in an insulation film formed on top of a semiconductor substrate, and a barrier metal film is formed on the surface of the trench. After a copper or copper alloy film is formed on the barrier metal film, an oxygen absorption film in which a standard energy of formation of an oxidation reaction in a range from room temperature to 400° C. is negative, and in which an absolute value of the standard energy of formation is larger than that of the barrier metal film is formed, and the assembly is heated in a temperature range of 200 to 400° C. A semiconductor device can thereby be provided that has highly reliable wiring, in which the adhesion to the barrier metal film in the copper interface is enhanced, copper diffusion in the interface is suppressed, and electromigration and stress migration are prevented.

    Abstract: An interconnect structure for integrated circuits incorporates manganese silicate and manganese silicon nitride layers that completely surrounds copper wires in integrated circuits and methods for making the same are provided. The manganese silicate forms a barrier against copper diffusing out of the wires, thereby protecting the insulator from premature breakdown, and protecting transistors from degradation by copper. The manganese silicate and manganese silicon nitride also promote strong adhesion between copper and insulators, thus preserving the mechanical integrity of the devices during manufacture and use. The strong adhesion at the copper-manganese silicate and manganese silicon nitride interfaces also protect against failure by electromigration of the copper during use of the devices. The manganese-containing sheath also protects the copper from corrosion by oxygen or water from its surroundings.

    Abstract: A method for manufacturing a semiconductor device. In one example embodiment, a method for manufacturing a semiconductor device includes various steps. First, a dielectric layer is formed on the whole surface of a semiconductor substrate that includes an upper surface of a transistor. Next, a trench and a contact hole are formed by etching the dielectric layer so that the upper surface of the transistor is exposed. Then, a contact is formed by embedding a first conductive layer in the contact hole. Next, an etching stop layer is selectively forming on an upper part of the contact. Then, the semiconductor device is blanket-etched such that the first conductive layer remains in the trench. Next, the etching stop layer is removed. Finally, a metal line is formed by embedding a second conductive layer in the trench.

    Abstract: In forming a layer of a semiconductor wafer, a dielectric layer is deposited on the semiconductor wafer. The dielectric layer includes material having a low dielectric constant. Recessed and non-recessed areas are formed in the dielectric layer. A metal layer is deposited on the dielectric layer to fill the recessed areas and cover the non-recessed areas. The metal layer is then electropolished to remove the metal layer covering the non-recessed areas while maintaining the metal layer in the recessed areas.
