The present invention relates to a security screen and a manufacturing method thereof. The security screen comprises: a first film layer; and a blind layer in which shielding partition walls for blocking input images are repeatedly arranged at a distance from each other in parallel or in a lattice configuration at a predetermined angle. The shielding partition walls are constituted by repeatedly printing or transferring a light-absorbing color ink onto one or both surfaces of the first film layer. The security screen is fitted to the displays of image devices such as computer monitors, cash dispensers, navigation devices, mobile phones and PDAs or is fitted to the glass of buildings or the like, thereby making it impossible for the image being output on the display to be viewed by any third party positioned on the left, right, above or below who is not the user of the image device, and which makes the image clearer by preventing the phenomenon of blurring and the phenomenon of glare which occur, for example, when external light shines on devices and on glass or the like.

Provided is a lamp unit configured such that light emitted from a lamp is irradiated in a constant irradiation direction when the lamp unit is installed on one surface of a vehicle having a curvature. The lamp unit includes . Therefore, the lamp unit can be mounted in an easily modified manner according to the shape of an object on which the lamp unit is to be installed. In addition, since the lamp unit is fabricated in a simplified manner, the fabrication cost can be reduced.

A method of reworking a semiconductor substrate and a method of forming a pattern of semiconductor device using the same without damage to an organic anti-reflective coating (ARC) is provided. The method of reworking a semiconductor substrate includes forming a photoresist pattern on a substrate having the organic ARC formed thereon. An entire surface of the substrate having the photoresist pattern formed thereon may be exposed when a defect is present in the photoresist pattern. The entire-surface-exposed photoresist pattern may be removed by performing a developing process without damage to the organic ARC.

A method of forming a fine pattern includes forming pillar-shaped guides regularly arranged on a feature layer, forming a block copolymer layer on the feature layer around the pillar-shaped guides, phase separating the block copolymer layer, forming first domains regularly arranged on the feature layer with the pillar-shaped guides, forming a second domain on the feature layer surrounding the pillar-shaped guides and the first domains, removing the first domains, and forming holes corresponding with the first domains in the feature layer by etching the feature layer using the pillar-shaped guides and the second domain as etch masks. The block copolymer layer includes a polymer blend having first and second polymer blocks having first and second repeat units, respectively, a first homopolymer and a second homopolymer. The first domains include the first polymer block and the first homopolymer, and the second domain includes the second polymer block and the second homopolymer.

In a method of determining a focus position for a substrate exposure process and a substrate exposure apparatus capable of performing the same, a reticle having a light-transmitting region may be illuminated by an off-axis illumination light. A projected light, which is transmitted through the reticle and a projection optical system, may be detected by a light sensor disposed on a substrate stage. An intensity of the projected light measured at a light-receiving surface of the light sensor may vary in accordance with positions of the light-receiving surface. The focus position may be determined based on the variations in the intensity of the projected light.
