Abstract: Methods for HPC techniques are applied to the processing of site-isolated regions (SIR) on a substrate to form at least a portion of a TFT device used in display applications. The processing may be applied to at least one of gate dielectric deposition, gate dielectric patterning, metal-based semiconductor deposition, metal-based patterning, etch stop deposition, etch stop patterning, source/drain deposition, or source/drain patterning. The SIRs may be defined during the deposition process with uniform deposition within each SIR or the SIRs may be defined subsequent to the deposition of layers wherein the layers are deposited with a gradient in one or more properties across the substrate.

Abstract: In a “window-junction” formation process for Josephson junction fabrication, a spacer dielectric is formed over the first superconducting electrode layer, then an opening (the “window” is formed to expose the part of the electrode layer to be used for the junction. In an atomic layer deposition (ALD) chamber (or multi-chamber sealed system) equipped with direct or remote plasma capability, the exposed part of the electrode is sputter-etched with Ar, H2, or a combination to remove native oxides, etch residues, and other contaminants. Optionally, an O2 or O3 pre-clean may precede the sputter etch. When the electrode is clean, the tunnel barrier layer is deposited by ALD in-situ without further oxidant exposure.

Abstract: Methods and apparatus for processing using a remote plasma source are disclosed. The apparatus includes an outer chamber enclosing a substrate support, a remote plasma source, and a showerhead. A substrate heater can be mounted in the substrate support. A transport system moves the substrate support and is capable of positioning the substrate. The plasma system may be used to generate activated species. The activated species can be used to treat the surfaces of low-k and/or ultra low-k dielectric materials to facilitate improved deposition of diffusion barrier materials.

Abstract: A interconnect structure for superconducting devices uses a material with a high melting point for the superconductive wiring; examples include refractory metals such as niobium. Because the wiring is tolerant of high temperatures, the interlayer dielectric (e.g., amorphous silicon with or without small amounts of passivants such as hydrogen or fluorine) may be subjected to rapid thermal annealing to reduce defects by driving off excess hydrogen, and optionally partially crystallizing the material.

Abstract: Provided are resistive random access memory (ReRAM) cells and methods of fabricating them using metal organic chemical vapor deposition (MOCVD). Specifically, MOCVD is used to form an embedded resistor that includes two different nitrides. The first nitride may be more conductive than the second nitride. The concentrations of these nitrides may vary throughout the thickness of the embedded resistor. This variability may be achieved by changing flow rates of MOCVD precursors during formation of the embedded resistor. The second nitride may be concentrated in the middle of the embedded resistor, while the first nitride may be present at interface surfaces of the embedded resistor. As such, the first nitride protects the second nitride from exposure to other components and/or environments and prevents oxidation of the second nitride. Controlling the distribution of the two nitrides within the embedded resistor allows using new materials and achieving consistent performance of the embedded resistor.

Abstract: A method of fabricating a resistive random access memory (ReRAM) cell may include forming a set of nanolaminate structures over an electrode, such that each structure includes at least one first element oxide layer and at least one second element oxide layer. The overall set is operable as a resistive switching layer in a ReRAM cell. In this set, an average atomic ratio of the first element to the second element is different in at least two nanolaminate structures. This ratio may be less in nanolaminate structures that are closer to electrodes than in the middle nanolaminate structures. Alternatively, this ratio may increase from one end of the set to another. The first element may be less electronegative than the second elements. The first element may be hafnium, while the second element may be one of zirconium, aluminum, titanium, tantalum, or silicon.

High resistance interconnect lines can be used to partition the memory array can be partitioned into areas of high data retention and areas of low data retention. Variable gate voltages can be used in control transistors to store memory values having different data retention characteristics.

Abstract: Selective wet etching is used to produce feature sizes of reduced width in semiconductor devices. An initial patterning step (e.g., photolithography) forms a pillar of an initial width from at least a selected first layer and an overlayer. A wet etchant that is selective to the selected layer undercuts the sidewalls of the selected layer to a smaller width while leaving at least part of the overlayer in place to protect the top surface of the selected layer. The selected layer becomes a narrow “stem” within the pillar, and may have dimensions below the resolution limit of the technique used for the initial patterning. For some devices, voids may be intentionally left in a fill layer around the stem for electrical or thermal insulation.

Abstract: Provided are apparatus for high productivity combinatorial (HPC) processing of semiconductor substrates and HPC methods. An apparatus includes a showerhead and two or more self-controlled one-way valves connected to the showerhead and used for controlling flow of different processing gases into the showerhead. The self-controlled one-way valves are not externally controlled by any control systems. Instead, these valves open and close in response to preset conditions, such as pressure differentials and/or flow differentials. One example of such self-controlled one-way valves is a check valve. These valves generally allow the flow only in one direction, i.e., into the showerhead. Furthermore, lack of external controls and specific mechanical designs allow positioning these self-controlled one-way valves in close proximity to the showerhead thereby reducing the dead volume between the valves and the showerhead and also operating these valves at high temperatures.

Abstract: Provided are voltage controlling assemblies that may be operable as clocks and/or oscillators. A voltage controlling assembly may include a comparator and a variable resistance device connected to one differential signal node of the comparator. The other node may be connected to a capacitor. Alternatively, no capacitors may be used in the assembly. During operation of the voltage controlling assembly, the variable resistance device changes its resistance between two different resistive states. The change from a low to a high resistive state may be associated with a voltage spike at the differential signal node of the comparator and trigger a response from the comparator. This resistance change may have a delay determining an operating frequency of the voltage controlling assembly. Specifically, the variable resistance device in the low resistive state may be kept for a period of time at a certain voltage before it switches into the high resistive state.
