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.

A probe for detecting minute physical behavior comprises a lever member, particularly in the form of a cantilever, formed of a monocrystalline silicon layer and a tip in the form of one-end-supported beam which is bowed and formed upon the lever member. The probe is manufactured by forming a film of a material with low density and high elasticity on the silicon layer of an SOI substrate, then oxidizing part of the silicon layer and removing the oxidized portion to form a tip with the material as a so-called bird's beak, and finally the SOI substrate is worked to form the cantilever shape of the lever member. The probe can be used for an information recording/reproducing device with good traceability even in high speed scanning over a recording medium.

A female mold substrate used for the production of a microprobe tip or probe detecting a tunneling current or weak force includes a substrate provided with a recess section and a heat-flowable layer having flowability by heat treatment formed on the substrate and covering the recess. The female mold substrate is made by forming a recess section on the top surface of a substrate and forming a heat-flowable layer on the top surface of the substrate including the recess section. A microprobe tip detecting a tunneling current or weak force is made by forming a tip material layer on the female mold substrate and transferring the tip of material layer onto another substrate.

A micro-tip for detecting tunneling current, micro force or magnetic force is manufactured as follows. A recess portion is formed on the surface of a first substrate. A peeling layer are formed on the substrate including the recess of the first substrate. A micro-tip is formed on the peeling layer of the first substrate. A joining layer is formed on a second substrate. The micro-tip on the peeling layer including the recess in the first substrate is transferred onto the joining layer on the second substrate. The peeling layer mainly consists of an oxide or a nitride, of a metal element, a semi-metal element or a semiconductor element.

A micro-tip is manufactured by forming a recess portion on a first substrate consisting of monocrystalline silicon for forming a tip. A peeling layer is formed on the recess portion, and contact layer is formed on at least a portion other than the peeling layer on the substrate. A tip material layer is formed on the peeling layer and the contact layer. The tip material layer on the peeling layer is transferred onto a second substrate.

The tiltable-body apparatus including a frame member, a tiltable body, and a pair of torsion springs having a twisting longitudinal axis. The torsion springs are disposed along the twisting longitudinal-axis opposingly with the tiltable body being interposed, support the tiltable body flexibly and rotatably about the twisting longitudinal axis relative to the frame member, and include a plurality of planar portions, compliant directions of which intersect each other when viewed along a direction of the twisting longitudinal axis. A center of gravity of the tiltable body is positioned on the twisting longitudinal axis of the torsion springs.

There are provided a small optical deflector that can be driven at a high speed with a low voltage, provides a large angle of deflection, has a low distortion even in high speed operation and has a high static flatness of a reflective surface, and a method of producing the optical deflector. The optical deflector drives a movable plate relative to a supporting substrate to deflect a light incident on a reflective surface and has a configuration in which at least two recesses are formed in a surface of the movable plate on which the reflective surface is not formed, and a magnetic material is provided in the recesses.
