Abstract:
Described herein is an apparatus for manufacturing a semiconductor which comprises a chamber having a susceptor for attaching a processed product on the lower inner portion and a polarization spectral reflection module located in the upper portion of the chamber. The polarization spectral reflection module comprises: a light source for generating light; a beam splitter for receiving the light generated from the light source to reflect a portion; an objective polarizer for polarizing the light reflected by the beam splitter to irradiate a processed product on the susceptor; a reflective aperture in which the reflected polarized light reflected from the processed product counter-passes the object polarizer, a portion of the reflected polarized light passes through the beam splitter, and a portion of the reflected polarized light passed through the beam splitter passes through the reflective aperture; a blaze grating for reflecting the reflected polarized light passed through the reflective aperture; and an array director for sensing the reflected polarized light separated and reflected by the blaze grating.
Abstract:
An air purifying filter is provided to extend the life of an activated carbon fiber filter, construct the activated carbon fiber filter in a simple structure, and reduce operating and maintaining costs of the activated carbon fiber filter. An air purifying filter(100) comprises: a filter case(110) for accommodating the activated carbon fiber filter; an activated carbon fiber filter(120) installed in the filter case such that the activated carbon fiber filter can travel to adsorb and remove polluted gas components; a nanoparticle spray(140) for spraying the functional nanoparticles onto the activated carbon fiber filter to coat functional nanoparticles on a surface of the activated carbon fiber filter; and an ultraviolet lamp(150) for irradiating ultraviolet rays onto the activated carbon fiber filter. The filter case has an inlet(111) formed in a front side thereof, and an outlet(112) formed in a rear side thereof. The air purifying filter further comprises a pair of rollers(131,133) installed within the filter case and spaced apart from each other to run the activated carbon fiber filter.
Abstract:
PURPOSE: A method of forming an image of a semiconductor device and a method for inspecting defects of a semiconductor device using the same are provided to simply produce the final image of a specimen by selecting partial image frames of a plurality of image frames. CONSTITUTION: A semiconductor device having an interest area and a peripheral area is prepared(S110). A plurality of image frames, which includes the interest image and the peripheral area image respectively corresponding to the interest area and the peripheral area, is obtained(S120). At least a part of the plurality of image frames is selected(S130). The image of the semiconductor device is obtained by integrating selected image frames(S140).
