A photo thin film transistor having a photoconductive layer including a chalcogenide element and a unit cell of an image sensor using the same are provided. The photo thin film transistor includes a glass substrate; a photoconductive layer that is formed of GST including a chalcogenide element, is disposed on the glass substrate, and absorbs light and generates an optical current; a source electrode and a drain electrode that are formed on respective sides of the photoconductive layer and form a path for the optical current generated by the photoconductive layer; a gate insulating layer formed on the photoconductive layer; and a gate electrode that is formed on the gate insulating layer and turns the optical current on or off. The photo thin film transistor includes amorphous GST including a chalcogenide element forming a photoconductive layer, thereby providing very high photoconductivity.

A layer structure comprising substrate, a metal layer, a first amorphous silicon layer, an insulating layer, and a second amorphous silicon layer, and a method of crystallizing the second amorphous silicon layer by irradiating single pulse laser to the layer structure are provided. The method provides an effect of forming large grain of amorphous silicon as good as using dual pulse laser or higher just by using single pulse laser without additional optical system. A semiconductor device employing the layer structure maximizes an electron mobility.

Provided is a fingerprint sensor using a microlens including the microlens changing a path of light reflected by a fingerprint structure, and an optical-TFT checking the fingerprint structure from the light whose path is changed. Since the microlens including the spherical lens to change the path of light is provided, the amount of light incident on the light measuring area can be maximized. Also, since the noise such as dispersed light is exhausted by the spherical lens outside the light measuring area, the effect by the noise can be minimized.

Disclosed herein is an electro-magnetic contactor and an electro-magnetic contactor monitoring system. The present disclosure may sense and display the status of input power that supplies electric energy to a power input end of the electro-magnetic contactor in real time, and when a failure occurs to generate a low voltage or over voltage, it may be sensed in real time to notify it to a user or the like, thereby allowing the user to monitor the status from a remote location. According to the present disclosure, it may be possible to prevent a load from being damaged by a fire due to a phenomenon of chattering in the electro-magnetic contactor, and eradicating a phenomenon that a coil of the contactor is damaged by a fire due to the over voltage, and minimizing losses that can be caused in a factory management system.

Provided is a method of fabricating a near-field optical probe adapted to a near-field scanning optical microscopy and a near-field information storage device, in which a cantilever and an optical tip are provided in one body and the optical tip is arranged to face the upper portion of the substrate. High-concentrated boron ions are implanted into an uppermost silicon layer of a silicon on insulator (SOI) substrate, and a silicon layer into which boron ions are implanted while the silicon inside the tip is etched to form the hole to act as an etch stop layer, thereby easily removing the silicon inside the tip even with the cantilever exposed, and simplifying the process due to the simultaneous fabrication of the cantilever and the tip.

The present invention relates to a head for recording/reading optical data and method of manufacturing the same. The present invention completely buries an aperture with a material a third non-linear coefficient of which is great in order to induce self-focusing. Thus, the present invention can reduce the amount of beam by about one half wavelength and focus the beam in a parabolic shape having almost no optical loss. Therefore, the present invention can improve the transmissivity of the probe by several hundreds times compared to a conventional optical fiver probe, by effectively exciting a near-field scanning optical microscopy for the aperture at an end portion of the probe.
