  • Patent number: 11987740
    Abstract: Provided are a silicon nitride film etching composition, a method of etching a silicon nitride film using the same, and a manufacturing method of a semiconductor device. Specifically, a silicon nitride film may be highly selectively etched as compared with a silicon oxide film, and when the composition is applied to an etching process at a high temperature and a semiconductor manufacturing process, not only no precipitate occurs but also anomalous growth in which the thickness of the silicon oxide film is rather increased does not occur, thereby minimizing defects and reliability reduction.
    Type: Grant

  • Patent number: 11939505
    Abstract: Provided are a silicon nitride film etching composition, a method of etching a silicon nitride film using the same, and a manufacturing method of a semiconductor device. Specifically, a silicon nitride film may be stably etched with a high selection ratio relative to a silicon oxide film, and when the composition is applied to an etching process at a high temperature and a semiconductor manufacturing process, not only no precipitate occurs but also anomalous growth in which the thickness of the silicon oxide film is rather increased does not occur, thereby minimizing defects and reliability reduction.

  • Publication number: 20230368370
    Abstract: An apparatus includes one or more light source groups, a camera; one or more memories configured to store one or more first images acquired in advance, and one or more processors communicatively connected to the one or more light source groups, the camera, and the one or more memories, wherein the one or more processors are configured to acquire a second image by controlling a first light source group among the one or more light source groups and the camera and irradiating light beams to a substrate on which an object is coated, and determine a coating state of the object based on the one or more first images and the second image.
