Exemplary methods of fabricating high quality quantum computing components are described. The methods include removing native oxide from a deposition surface of a silicon substrate in a cleaning chamber of a processing system, and transferring the silicon substrate under vacuum to a deposition chamber of the processing system. The methods further include depositing an aluminum layer on the deposition surface of the silicon substrate in the deposition chamber, where an interface between the aluminum layer and the deposition surface of the silicon substrate is oxygen free.

High quality quantum computer components

The present invention provides an energy storage device comprising a cathode region or other element. The device has a major active region comprising a plurality of first active regions spatially disposed within the cathode region. The major active region expands or contacts from a first volume to a second volume during a period of a charge and discharge. The device has a catholyte material spatially confined within a spatial region of the cathode region an spatially disposed within spatial regions not occupied by the first active regions. The device has a protective material formed overlying exposed regions of the cathode material to substantially maintain the sulfur species within the catholyte material. Also included is a novel dopant configuration of the LiMPS(LMPS) [M=Si, Ge, and/or Sn] containing material.

The disclosure herein relates to rechargeable batteries and solid electrolytes therefore which include lithium-stuffed garnet oxides, for example, in a thin film, pellet, or monolith format wherein the density of defects at a surface or surfaces of the solid electrolyte is less than the density of defects in the bulk. In certain disclosed embodiments, the solid-state anolyte, electrolyte, and catholyte thin films, separators, and monoliths consist essentially of an oxide that conducts Liions. In some examples, the disclosure herein presents new and useful solid electrolytes for solid-state or partially solid-state batteries. In some examples, the disclosure presents new lithium-stuffed garnet solid electrolytes and rechargeable batteries which include these electrolytes as separators between a cathode and a lithium metal anode.

Methods and apparatus for processing a substrate is provided herein. For example, a method for processing a substrate comprises depositing a silicide layer within a feature defined in a layer on a substrate, forming one of a metal liner layer or a metal seed layer atop the silicide layer within the feature via depositing at least one of molybdenum (Mo) or tungsten (W) using physical vapor deposition, and depositing Mo using at least one of chemical vapor deposition or atomic layer deposition atop the at least one of the metal liner layer or the metal seed layer, without vacuum break.

Methods and apparatus for processing a substrate

A method of fabricating a device including a superconductive layer includes depositing a seed layer on a substrate, exposing the seed layer to an oxygen-containing gas or plasma to form a modified seed layer, and after exposing the seed layer to the oxygen-containing gas or plasma depositing a metal nitride superconductive layer directly on the modified seed layer. The seed layer is a nitride of a first metal, and the superconductive layer is a nitride of a different second metal.
