  • Publication number: 20200098593
    Abstract: A washing method, a washing device, a storage medium, and a washing composition for enabling effective removal of a layer to be processed by decomposing or degenerating the layer to be processed at a higher temperature than conventionally. In a state where a substrate provided with a layer to be processed is heated, the substrate is supplied with vapor of a component that can decompose the layer to be processed, and thereafter the layer to be processed that has reacted with the component is removed from the substrate. As the component, a nitric acid or a sulfonic acid is preferable. As the sulfonic acid, a fluorinated alkyl sulfonic acid is preferable.

  • Publication number: 20190265954
    Abstract: A design pattern discovery assist apparatus presents one or more second node candidates, which are one or more candidates of a second node, when a first node is selected regarding a flow in the middle of being edited. The first node is any node corresponding to one type of node between an input node and an output node. The second node is a node corresponding to the first node among nodes corresponding to any type between the other type of node between the input node and the output node and an input/output node, which serves as both the input and the output nodes. When any second node candidate is selected as the second node, the assist apparatus presents one or more partial flow candidates which are one or more candidates of a partial flow between the first node and the second node.
