    摘要: A substrate processing method includes preparing a substrate having a low-k interlayer dielectric film as a to-be-etched film and a photoresist film, formed on the low-k interlayer insulating film, serving as an etching mask with a predetermined circuit pattern; etching the low-k interlayer insulating film through the photoresist film to form grooves and/or holes in the low-k interlayer insulating film; ashing the photoresist film by using hydrogen radicals generated by bring a hydrogen-containing gas into contact with a catalyst of a high temperature; and recovering damage to the low-k interlayer insulating film due to the ashing by supplying a specific recovery gas. The method further includes recovering damage to the low-k interlayer insulating film due to the etching by supplying a specific recovery gas.
