  • Publication number: 20200058497
    Abstract: Embodiments described herein relate to methods of controlling the uniformity of SiN films deposited over large substrates. When the precursor gas or gas mixture in the chamber is energized by applying radio frequency (RF) power to the chamber, the RF current flowing through the plasma generates a standing wave effect (SWE) in an inter-electrode gap. SWEs become significant as substrate or electrode size approaches the RF wavelength. Process parameters, such as process power, process pressure, electrode spacing, and gas flow ratios all affect the SWE. These parameters can be altered in order to minimize the SWE problem and to achieve acceptable thickness and properties uniformities. In some embodiments, methods of depositing a dielectric film over a large substrate at various process power ranges, at various process pressure ranges, at various gas flow rates, while achieving various plasma densities will act to reduce the SWE, creating greater plasma stability.

  • Publication number: 20190382891
    Abstract: Embodiments described herein provide an apparatus for providing an inductance at positions that correspond to positions of substrate support pins. The apparatus includes one or more substrate support pins. Each substrate support pin includes a head portion, a first portion, and a second portion. The second portion is an inductor that provides inductance at positions of substrate support pins. The inductance provided by the second portion of the substrate support pin changes the impedance to match the impedance at areas of the substrate support without the substrate support pins. With matched impedance, the plasma density over the areas of the substrate support with the support pins and without the support pins is uniform, leading to improved film thickness uniformity. The uniform film thickness thus reduces or eliminates clouding or the “mura effect”.

  • Patent number: 10461359
    Abstract: Provided are electrode layers for use in rechargeable batteries, such as lithium ion batteries, and related fabrication techniques. These electrode layers have interconnected hollow nanostructures that contain high capacity electrochemically active materials, such as silicon, tin, and germanium. In certain embodiments, a fabrication technique involves forming a nanoscale coating around multiple template structures and at least partially removing and/or shrinking these structures to form hollow cavities. These cavities provide space for the active materials of the nanostructures to swell into during battery cycling. This design helps to reduce the risk of pulverization and to maintain electrical contacts among the nanostructures. It also provides a very high surface area available ionic communication with the electrolyte. The nanostructures have nanoscale shells but may be substantially larger in other dimensions.

In certain embodiments, an active material includes one or more high capacity active materials, such as silicon, tin, and germanium. These materials tend to swell during cycling and may loose mechanical and/or electrical connection to the substrate. A flexible intermediate layer may compensate for swelling and provide a robust adhesion interface. Provided also are novel methods of fabricating electrodes containing one or more intermediate layers.
