Pattern formation method and method of manufacturing semiconductor device

A pattern formation method includes forming an organic film on a substrate, processing the organic film to form an organic film pattern, exposing the organic film pattern to an organic gas, and exposing the organic film pattern to a metal-containing gas, and after (i) exposing the organic film patte...

Summary:A pattern formation method includes forming an organic film on a substrate, processing the organic film to form an organic film pattern, exposing the organic film pattern to an organic gas, and exposing the organic film pattern to a metal-containing gas, and after (i) exposing the organic film pattern to the organic gas and (ii) exposing the organic film pattern to the metal-containing gas, treating the organic film pattern with an oxidizing agent.
