  • Patent number: 11351078
    Abstract: A method for cleaning and sterilizing an excreta handling device includes: positioning one end and the other end of the suction pipe on the same line; driving the pump to supply the cleaning water to a preset water level in the inner space through the first nozzle part; and maintaining, for a predetermined time, a state in which the cleaning water has been supplied to the preset water level, and then driving the suction part to suck the cleaning water contained in the inner space.
    Type: Grant

  • Patent number: 9627216
    Abstract: Embodiments of methods for forming features in a silicon containing layer of a substrate disposed on a substrate support are provided herein. In some embodiments, a method for forming features in a silicon containing layer of a substrate disposed on a substrate support in a processing volume of a process chamber includes: exposing the substrate to a first plasma formed from a first process gas while providing a bias power to the substrate support, wherein the first process gas comprises one or more of a chlorine-containing gas or a bromine containing gas; and exposing the substrate to a second plasma formed from a second process gas while no bias power is provided to the substrate support, wherein the second process gas comprises one or more of an oxygen-containing gas or nitrogen gas, and wherein a source power provided to form the first plasma and the second plasma is continuously provided.

  • Patent number: 9390923
    Abstract: Methods for removing residual polymers formed during etching of a boron-doped amorphous carbon layer are provided herein. In some embodiments, a method of etching a feature in a substrate includes: exposing a boron doped amorphous carbon layer disposed on the substrate to a first plasma through a patterned mask layer to etch a feature into the boron doped amorphous carbon layer, wherein the first plasma is formed from a first process gas that reacts with the boron doped amorphous carbon layer to form residual polymers proximate a bottom of the feature; and exposing the residual polymers to a second plasma through the patterned mask layer to etch the residual polymers proximate the bottom of the feature, wherein the second plasma is formed from a second process gas comprising nitrogen (N2), oxygen (O2), hydrogen (H2), and methane (CH4).

  • Patent number: 9064812
    Abstract: Embodiments of methods for etching a substrate include exposing the substrate to a first plasma formed from an inert gas; exposing the substrate to a second plasma formed from an oxygen-containing gas to form an oxide layer on a bottom and sides of a low aspect ratio feature and a high aspect ratio feature, wherein the oxide layer on the bottom of the low aspect ratio feature is thicker than on the bottom of the high aspect ratio feature; etching the oxide layer from the bottom of the low and high aspect ratio features with a third plasma to expose the bottom of the high aspect ratio feature while the bottom of the low aspect ratio feature remains covered; and exposing the substrate to a fourth plasma formed from a halogen-containing gas to etch the bottom of the low aspect ratio feature and the high aspect ratio feature.
