  • Patent number: 10620031
    Abstract: An apparatus for the detecting the amount of material remaining in a container is disclosed. This apparatus may be beneficial when used with a semiconductor processing device, especially when the material is in the solid phase. The apparatus measures the impedance between an electrode disposed in the container, and the outside of the container to make a determination regarding how full the container may be. In certain embodiments, only the magnitude of the impedance is used for this calculation. In other embodiments, the magnitude and phase of the impedance are used. This may be used to determine the topology of the material within the container.

  • Patent number: 10535527
    Abstract: A method for forming a film on a substrate in a semiconductor process chamber includes forming a first layer on the substrate using a plasma enhanced process and a gas compound of a chloride-based gas, a hydrogen gas, and an inert gas. The process chamber is then purged and the first layer is thermally soaked with a hydrogen-based precursor gas. The process chamber is then purged again and the process may be repeated with or without the plasma enhanced process until a certain film thickness is achieved on the substrate.

  • Patent number: 9162930
    Abstract: The present invention generally relates to a doped aluminum nitride hardmask and a method of making a doped aluminum nitride hardmask. By adding a small amount of dopant, such as oxygen, when forming the aluminum nitride hardmask, the wet etch rate of the hardmask can be significantly reduced. Additionally, due to the presence of the dopant, the grain size of the hardmask is reduced compared to a non-doped aluminum nitride hardmask. The reduced grain size leads to smoother features in the hardmask which leads to more precise etching of the underlying layer when utilizing the hardmask.
