摘要:
A pattern forming apparatus for forming a pattern on a substrate includes a first exposure section capable of conducting pattern exposure for a predetermined line width, a second exposure section for conducting pattern exposure for a line width greater than the predetermined linewidth of the first exposure section, and a device for detecting the relative positional relationship between the first exposure section and the second exposure section. Pattern exposure is conducted by using the first exposure section and the second exposure section on the basis of the detected positional relationship.
摘要:
An alignment method for an exposure mask and an object to be exposed, wherein exposure is carried out while the exposure mask having a light blocking film formed at a membrane portion thereof is closely contacted to the object to be exposed and light from a light source is projected to the object to be exposed, through the exposure mask, and wherein alignment of the exposure mask and the object to be exposed is carried out prior to the exposure, the method comprising the steps of preparing an exposure mask having a light blocking film provided on a base material constituting the membrane portion and having a structure for performing position detection, flexing the membrane portion and detecting, by use of the structure, a relative position of the exposure mask and the object to be exposed, in a state in which the exposure mask is contacted to the object to be exposed, and aligning the exposure mask and the object to be exposed, with each other, on the basis of a result of the position detection.

A near-field photoresist for formation of a fine pattern with by near-field exposure includes an alkali-soluble novalac resin, a diazyde-type photosensitizer which is photoreactive by near-field exposure, a photoacid generator which generates acid by the near-field exposure, and a solvent.
摘要:
A photolithography method using near-field light includes a step of controlling the position of an exposure mask and an object to be processed so as to make the object to be located in a region where near-field light is present, and a step of exposing the object to near-field light while controlling the intensity of such light as a function of the aperture density of the exposure mask. The intensity of near-field light is controlled by modifying the aperture width or modifying the transmissivity of the exposure mask depending on the aperture density.

摘要:
A sensor device is formed from a metal film having a plurality of openings, a sensor material positioned within each of the openings, a light source that emits light having a first wavelength, and a light detector that detects light emitted from the light source and transmitted through or reflected from the openings. The plurality of openings are arranged periodically in a first direction in the metal film, and both a size of each of the plurality of openings and an interval thereof in the first direction are equal to or less than the wavelength of the light.
摘要:
A near field light probe is capable of emanating a near field light having a sufficient intensity while allowing reduction of aperture size to improve resolution. The near field light probe can be incorporated in a near-field optical microscope, a near field light lithography apparatus, and a near field light storage apparatus. A near field light probe has a configuration in which a light-blocking film is formed with an aperture having slits surrounding the major opening. Light emitted from a light source is coupled into the probe from one side of the light-blocking film, the light being polarized in a predetermined direction with respect to the slits so that a near field light emanates from the major opening.

A near-field optical probe comprises a micro-aperture for irradiating and/or detecting evanescent light through the front end of the probe, an elastically deformable cantilever supporting the micro-aperture at the free end thereof, and a surface plasmon polariton waveguide arranged on the cantilever to guide light from a light source to the micro-aperture and/or to guide light from a light source introduced through the micro-aperture.
