Patent number: 7570130Abstract: In certain embodiments, an apparatus for providing a fixed impedance transformation network for driving a plasma chamber includes a pre-match network adapted to couple between an Active RF match network and a plasma chamber load associated with the plasma chamber. The pre-match network includes (1) a first capacitive element; (2) an inductive element connected in parallel with the first capacitive element to form a parallel circuit that presents a stepped-up impedance to an output of the Active RF match network such that a voltage required to drive the plasma chamber load is reduced; and (3) a second capacitive element coupled to the parallel circuit and adapted to couple to the plasma chamber load. The second capacitive element reduces or cancels at least in part a reactance corresponding to an inductance associated with the plasma chamber load. Numerous other aspects are provided.Type: GrantFiled: July 11, 2005Date of Patent: August 4, 2009Assignee: Applied Materials, Inc.Inventors: Carl A. Sorensen, John M. White, Suhail Anwar

Patent number: 7569501Abstract: Embodiments of the invention provide methods for forming hafnium materials, such as oxides and nitrides, by sequentially exposing a substrate to hafnium precursors and active oxygen or nitrogen species (e.g., ozone, oxygen radicals, or nitrogen radicals). The deposited hafnium materials have significantly improved uniformity when deposited by these atomic layer deposition (ALD) processes. In one embodiment, an ALD chamber contains an expanding channel having a bottom surface that is sized and shaped to substantially cover a substrate positioned on a substrate pedestal. During an ALD process for forming hafnium materials, process gases form a vortex flow pattern while passing through the expanding channel and sweep across the substrate surface. The substrate is sequentially exposed to chemical precursors that are pulsed into the process chamber having the vortex flow.Type: GrantFiled: May 31, 2006Date of Patent: August 4, 2009Assignee: Applied Materials, Inc.Inventors: Craig R.
