Near-field exposure mask, method of producing that mask, near-field exposure apparatus having that mask, and resist pattern forming method
Abstract:
Disclosed is a near-field exposure mask having a light blocking layer formed on a substrate, the light blocking layer having an opening with an opening width narrower than a wavelength of an exposure light source, wherein exposure of an object to be exposed is carried out by use of near-field light to be produced at the opening while the exposure mask and the object to be exposed are placed in contact with each other, an important feature residing in that the light blocking layer is provided by a film that contains silicon in a range from 50% to 100% in terms of mole fraction.
