    • In the first option of the present invention, a semiconductor structure is provided and an overlying titanium nitride barrier layer is deposited thereon at about 100° C. At least Al and Cu is sputtered over the titanium nitride barrier layer from about 270 to 300° C. to form an Al—Cu alloy containing metal layer. The sputtered Al—Cu alloy containing metal layer is promptly cooled at a cooling rate greater than about 100° C./minute to a temperature below 200° C. to form a Al—Cu alloy containing metal layer having minimal CuAl2 grain growth. The semiconductor structure is removed from the cooling chamber and the semiconductor structure is processed further below 200° C. to form semiconductor device precursors. In the second option of the present invention, a semiconductor structure having an overlying barrier layer is provided. At least Al and Cu is sputtered over the barrier layer at a first temperature to form an Al—Cu alloy containing metal layer having CuAl2 grains of a first average size. The semiconductor structure is processed and then heated to a second temperature to dissolve the CuAl2 grains of a first average size then rapidly cooling to a third temperature whereby the CuAl2 grains formed have a second average size within the Al—Cu alloy containing metal layer. The second average size CuAl2 grains being less than the first average size CuAl2 grains.
    • 在本发明的第一种选择中,提供了一种半导体结构,并在其上沉积了大约100℃的上覆氮化钛阻挡层。至少Al和Cu溅射在氮化钛阻挡层上约270-300℃ 以形成含有金属层的Al-Cu合金。 将溅射的含有Al-Cu合金的金属层以大于约100℃/分钟的冷却速度迅速冷却到低于200℃的温度,以形成含有最小CuAl 2晶粒生长的金属层的Al-Cu合金。 将半导体结构从冷却室中移除,半导体结构进一步在200℃以下进行处理以形成半导体器件前体。 在本发明的第二个选择中,提供了具有上覆阻挡层的半导体结构。 在第一温度下至少将Al和Cu溅射在阻挡层上,以形成含有具有第一平均尺寸的CuAl 2晶粒的金属层的Al-Cu合金。 将半导体结构加工,然后加热至第二温度以溶解第一平均尺寸的CuAl 2晶粒,然后快速冷却至第三温度,由此形成的CuAl 2晶粒在含有Al-Cu合金的金属层内具有第二平均尺寸。 第二平均尺寸CuAl2晶粒小于第一平均尺寸CuAl2晶粒。
