Abstract
A substrate processing method forming an oxynitride film by nitriding an oxide film formed on a silicon substrate includes a nitridation processing step that nitrides a surface of the oxide film by radicals or ions formed by exciting a nitrogen gas by microwave-excited plasma, the nitridation processing is conducted at a substrate temperature of 500° C. or less by setting an electron temperature of the microwave-excited plasma to 2 eV or less, and by setting the resident time of oxygen in the processing space in which the substrate to be processed is held, to two seconds or less.
