ABSTRACT:
The use of a positive resist composition that includes a resin with a specific structure improves the resolution and yields a resist pattern with a favorable shape. In addition, when a resist layer is formed on either a magnetic film or a metallic oxidation prevention film formed on the magnetic film, the layer is less prone to tailing and undercutting phenomena.
