摘要:
In a plasma processing method of dry-etching of a magnetic film having a thickness of 200 nm to 500 nm, a plasma processing method of dry-etching of a sample having the magnetic film on which a multilayered film including a resist film, an non-organic film underlying the resist film, a Cr film underlying the non-organic film, and an Al2O3 film underlying the Cr film.
