A technique can control the dimensions of an opening. A plasma processing method includes (a) providing a substrate including an etching target layer, and a mask layer located on an upper surface of the etching target layer and having a side surface defining at least one opening on the upper surface of the etching target layer and an extension from the side surface to at least a portion of the upper surface of the etching target layer, (b) forming a deposition layer on at least the side surface of the mask layer, and (c) at least partially etching the deposition layer using plasma generated from a first process gas to reduce a thickness of the deposition layer. The first process gas contains a gas for etching the etching target layer, and (c) is performed until the etching target layer is partially etched in a depth direction to remove the extension.

A substrate processing apparatus includes a chamber; a substrate support disposed in the chamber; a gas supply that supplies a gas into the chamber; and a controller that controls an overall operation of the substrate processing apparatus. The controller executes a process including: (a) placing a substrate on the substrate support, the substrate including an etching layer and a patterned mask on the etching layer; (b) forming a film on the patterned mask; (c) forming a reaction layer on the film; and (d) removing the reaction layer by applying energy to the reaction layer. In the step (c) a temperature of the substrate is set according to a thickness of the reaction layer to be formed.

Substrate processing method and substrate processing system

An apparatus which selectively etches a first region with respect to a second region made of a material different from that of the first region. The apparatus is controlled to perform a first step for generating, in a processing container housing a workpiece to be treated, a plasma of a treatment gas from a gas supply including a fluorocarbon gas, an oxygen-containing gas, and an inert gas, and forming a deposit including fluorocarbon on the object to be treated, and a second step for etching the first region with radicals of the fluorocarbon included in the deposit. The apparatus is also controlled to perform the first step and the second step repeatedly.

Etching apparatus

An etching method includes forming a film on a surface of a substrate having a region to be etched and a mask. The mask is provided on the region and includes an opening that partially exposes the region. The film is made of the same material as that of the region. The etching method further includes etching the region.

Etching method, substrate processing apparatus, and substrate processing system

A plasma processing apparatus in the present disclosure includes a plasma processing chamber, a gas supply, a power supply, and a controller. The controller causes (a) forming a first film on side walls of an opening of a processing target using the plasma so that the first film has different thicknesses along a spacing between pairs of side walls facing each other, and (b) forming a second film by performing a film forming cycle one or more times after (a) so that the second film has different thicknesses along the spacing between the pairs of side walls facing each other.

A substrate processing method includes: providing a substrate including a mask; forming a film on the mask; forming a reaction layer on a surface layer of the film; and removing the reaction layer by applying energy to the reaction layer.

With respect to an inference method performed by at least one processor, the method includes inputting, by the at least one processor, into a learned model, non-processed object image data of a second object and data related to a second process for the second object, and inferring, by the at least one processor using the learned model, processed object image data of the second object on which the second process has been performed. The learned model has been trained so that an output obtained in response to non-processed object image data of a first object and data related to a first process for the first object being input approaches processed object image data of the first object on which the first process has been performed.

An organic compound constituting the organic film is generated by polymerization of the first organic compound and the second organic compound.
