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.

A near-field photomask includes a light shield film having openings to constitute a light shield portion. The photomask can be used to expose an exposure target with near-field light generated through the openings. The openings formed in the light shield film include two or more parallel rows of first slit openings each having a width smaller than 100 nm, and two or more parallel rows of second slit openings each having a width smaller than 100 nm, which extend perpendicularly to the rows of first slit openings while interlinking at least two of the rows of first slit openings. A near-field exposure apparatus includes the near-field photomask with a positioning unit and a source for illuminating polarized light parallel to the first slit openings for forming a latent-dot-image on an exposure target only where a second slit opening crosses the light shield portion on the near-field photomak.
摘要:
A method for exposing a workpiece on the basis of near-field light escaping from an exposure mask having a light blocking film with a plurality of rectangular openings. The method includes protecting non-polarized near-field exposure light from a light source through the openings of the exposure mask to perform exposure of a pattern on the workpiece. The widths of the rectangular openings are smaller than that at a cross-point between a first curve on a coordinate of widths of the openings versus a near-field light intensity for an incident-light electric-field direction perpendicular to a lengthwise direction of a small-opening pattern and a second curve on the same coordinate for an incident-light electric-field direction parallel to the lengthwise direction of the small-opening pattern.

Disclosed is an exposure method and apparatus, an exposure mask and a device manufacturing method, wherein a first surface of a light blocking member having a plurality of openings formed in a mutually adjoining relation is placed at an exposure object side, and light is projected to the light blocking member from its second surface side so that exposure of the exposure object is carried out on the basis of near field light leaking from the openings. For exposure, interference is caused between surface plasmon polariton waves passing respectively through adjacent openings and going around to the first surface side, and, on the basis of it, a portion having a decreased light intensity is produced in the exposure object so that the exposure is carried out by use of the decreased light intensity portion.
摘要:
A probe for detecting light or irradiating light comprises a cantilever supported at an end thereof by a substrate, a hollow tip formed at a free end of the cantilever, a microaperture formed at the end of the tip, and a hollow waveguide formed inside the cantilever. A method for producing a probe for light detection or light irradiation which comprises the steps of working a substrate to form a groove therein, forming a flat plate-shaped cover portion on the groove to form a hollow waveguide having an opening in a part thereof, forming a hollow tip having a microaperture on the opening, and removing a part of the substrate by etching, to form a cantilever.

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.
摘要:
An optical prove for detecting or irradiating evanescent light is manufactured by forming a film having a regulated film thickness on a substrate, then forming a recess from the rear surface of the substrate, and forming a through hole in the film from the side of the recess by etching. The obtained optical probe has a micro-aperture at the tip of the through hole and usually, a plurality of optical probes each having a micro-aperture of uniform profile are formed on a single substrate. In the recess, light-receiving or light-irradiating means may be provided.
摘要:
A method for recording and/or reproducing images includes a step of performing a two dimensional scanning on a recording medium with a probe electrode which relatively returns in the X direction for the main scanning and in the Y direction for sub-scanning. The main scanning of the probe is performed at a frequency which is one positive integerth of the horizontal synchronous frequency of the image signal so as to enable the period required for returning of the probe electrode to be matched with the blanking period of the image signal. Thus, it is possible to avoid any data recording and reproducing operations during the period required for returning of the scanning probe electrode.
