摘要： In a substrate processing method, a polysilicon layer 38 on a wafer W is etched with a bromine cation 45a and a bromine radical 45b in plasma generated from a processing gas containing a hydrogen bromide gas, an oxygen gas, and a nitrogen trifluoride gas, and then, is ashed with an oxygen radical 46 and a nitrogen radical 47 in plasma generated from a processing gas containing an oxygen gas and a nitrogen gas. Thereafter, the polysilicon layer 38 is etched with a fluorine cation 48a and a fluorine radical 48b in plasma generated from a processing gas containing an argon gas and a nitrogen trifluoride gas. While the polysilicon layer 38 is ashed, an oxidation process is performed on a silicon bromide generated by etching the polysilicon layer 38 with the bromine cation 45a.
