Near field exposure mask, method of forming resist pattern using the mask, and method of producing device
摘要:
Provided are a near field exposure mask which can suppress heat generation of a mask during exposure and can also suppress variation in size of a resist pattern for each shot, and a resist pattern forming method using the same. The near field exposure mask includes a transparent mask matrix l0; a light shielding layer l2 formed above the transparent mask matrix l0 and containing silicon; a reflective layer l1 formed between the transparent mask matrix l0 and the light shielding layer l2; and an opening pattern provided in the reflective layer l1 and the light shielding layer l2 and being less in size than an exposure wavelength λ (nm), wherein the reflectance at an interface between the transparent mask matrix l0 and the reflective layer l1 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.
