    摘要: Embodiments of the invention provide encapsulated sputtering targets and methods for preparing such targets prior to a physical vapor deposition (PVD) process. In one embodiment, an encapsulated target for PVD is provided which includes a target layer containing lanthanum disposed on a backing plate and an encapsulation layer containing titanium disposed on or over the target layer. In one example, the target layer contains metallic lanthanum or lanthanum oxide and the encapsulation layer contains titanium. The encapsulation layer may have a thickness within a range from about 1,000 Å to about 2,000 Å. In another embodiment, a method for preparing an encapsulated target prior to a PVD process is provided which includes positioning an encapsulated target within a PVD chamber and exposing the encapsulation layer to a plasma while removing the encapsulation layer and revealing an upper surface of the target layer.

    摘要: Embodiments of the invention provide encapsulated sputtering targets for physical vapor deposition. In one embodiment, an encapsulated target contains a target layer containing a first metal or an oxide of the first metal disposed over a backing plate, an adhesion interlayer disposed between the target layer and the backing plate, and an encapsulation layer containing a second metal or an oxide of the second metal disposed over the target layer and an annular sidewall of the backing plate. The target layer is encapsulated by the backing plate and the encapsulation layer and the first metal is different than the second metal. In some examples, the first metal is lanthanum or lithium and the target layer contains metallic lanthanum, lanthanum oxide, or metallic lithium. In other examples, the second metal is titanium or aluminum and the encapsulation layer contains metallic titanium, titanium oxide, metallic aluminum, or aluminum oxide.

    摘要: A plasma sputter chamber and process for sputtering ruthenium and tantalum at low pressure or with self-sustained sputtering (SSS). The source magnetron is strongly unbalanced and of sufficient size to project the unbalanced magnetic field toward the wafer to increase the ionization probability. Sputter etch uniformity is increased by the use of an auxiliary magnet system rotating with the source magnetron but placed towards the center of rotation. It may be a larger, nearly balanced auxiliary magnetron with an outer polarity matching that of the source magnetron or an array of magnets of that polarity. An integrated process includes a directional deposition of the refractory metal and its nitride, a sputter etch, and a flash deposition.
