SUBSTRATE PROCESSING APPARATUS, SUBSTRATE PROCESSING METHOD AND STORAGE MEDIUM

摘要

Disclosed is a substrate processing apparatus which enables to efficiently remove an oxide layer and an organic material layer. Specifically disclosed is a substrate processing apparatus (10) wherein a third process unit (36) comprises a case-like process vessel (chamber) (50), a nitrogen gas supply system (190) and an ozone gas supply system (191). The ozone gas supply system (191) comprises an ozone gas supply unit (195) and an ozone gas supply pipe (196) connected to the ozone gas supply unit (195). The ozone gas supply pipe (196) has an ozone gas supply hole (197) having an opening facing to a wafer (W). The ozone gas supply unit (195) supplies an ozone (O3) gas into the chamber (50) through the ozone gas supply hole (197) via the ozone gas supply pipe (196).
