    Abstract:  半導体基板上方に形成された絶縁膜中の所定の領域に、配線を形成するための溝を形成し、その表面にバリアメタル膜を形成する。バリアメタル膜上に銅又は銅合金膜を形成した後、その膜上に室温から400°Cの範囲で酸化反応の標準生成エネルギーが負であり且つバリアメタル膜よりも標準生成エネルギーの絶対値が大きい酸素吸収膜を形成し、200乃至400°Cの範囲の温度で加熱する。これにより、バリアメタル膜と銅界面における密着性を向上させ、界面における銅拡散を抑制してエレクトロマイグレーション及びストレスマイグレーションの発生を防止し、信頼性の高い配線を有する半導体装置を提供することができる。

    Abstract: An interconnect structure having a dielectric layer with low dielectric constant is formed within an integrated circuit. In one embodiment of the invention, portions of a silicon dioxide layer (18) lying adjacent to a conductive interconnect (21) are removed to expose portions of a silicon nitride etch stop layer (16). A dielectric layer (22) having a low dielectric constant is then formed overlying the conductive interconnect (21) and the exposed portions of the silicon nitride etch stop layer (16). A portion of the dielectric layer (22) is then removed to expose the top surface of the conductive interconnect (21) to leave portions of the dielectric layer (22) between adjacent conductive interconnects (21). The resulting interconnect structure has reduced cross-talk between conductive interconnects (21) while avoiding prior art disadvantages of reduced thermal dissipation and increased mechanical stress.
