Patent ID: 7968256

Claim:
A near field exposure mask comprising: a transparent mask matrix l 0 ; a light shielding layer l 2 formed above the transparent mask matrix l 0 and containing silicon; a reflective layer l 1 formed between the transparent mask matrix l 0 and the light shielding layer l 2 ; and an opening pattern provided in the reflective layer l 1 and the light shielding layer l 2 and being less in size than an exposure wavelength λ (nm), wherein the reflectance at an interface between the transparent mask matrix l 0 and the reflective layer l 1 is higher than a reflectance at an interface between a transparent mask matrix and a light shielding layer formed on the transparent mask matrix and containing silicon of a near field exposure mask which has no reflective layer between the transparent mask matrix and the light shielding layer.
