  • Patent number: 12482663
    Abstract: A processing apparatus includes a first chamber having a gas first inlet and a first gas outlet, a plasma generator that generates a plasma in the first chamber, and a second chamber having a second gas inlet and a second gas outlet. A control unit controls the first inlet to provide a carbon containing gas to the first chamber and control the plasma generator to apply a first plasma to a silicon-containing film of a substrate to a first depth. The control unit controls the second gas inlet to apply another gas inside the second chamber and deposit a second part of the protection film over the first part of the protection film. The control unit controls a supply of a fluorocarbon gas through the first gas inlet and control the plasma generator to generate a second plasma to etch the silicon-containing film to a second depth.

  • Publication number: 20250285020
    Abstract: In this data presentation method, first, feature values of multiple pieces of data 9 are calculated. Subsequently, a distance d between the pieces of data 9 in a feature value space S defined on the basis of the feature values is calculated. Then, the data 9 is selected from a dataset 90 on the basis of the calculated distance d, and is presented to a user. Thus, the data 9 can be presented to the user in the manner corresponding to the distance d between the pieces of data 9 in the feature value space S. Therefore, the user can efficiently perform a process of labelling each of the multiple pieces of data 9.
