    摘要: Embodiments of the invention generally relate to a process kit for a semiconductor processing chamber, and a semiconductor processing chamber having a kit. More specifically, embodiments described herein relate to a process kit including a cover ring, a shield, and an isolator for use in a physical deposition chamber. The components of the process kit work alone and in combination to significantly reduce particle generation and stray plasmas. In comparison with existing multiple part shields, which provide an extended RF return path contributing to RF harmonics causing stray plasma outside the process cavity, the components of the process kit reduce the RF return path thus providing improved plasma containment in the interior processing region.

    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: Provided apparatus and methods for back side passivation of a substrate. The systems comprise an elongate support with an open top surface forming a support ring so that when a substrate is on the support ring, a cavity is formed within the elongate support. A plasma generator is coupled to the cavity to generate a plasma within the cavity to deposit a passivation film on the back side of the substrate.

    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.
