Abstract:
The present invention aims to provide a reflective photomask blank which can be used for providing a photomask having a structure by which a life span of the photomask can be extended by minimizing damage on a film constituting the EUV photomask. The reflective photomask includes: a multi-reflection film; a capping layer which is formed on the multi-reflection film and includes transition metals; a passivation film which contacts at least a portion of the capping layer on a side opposite to the multi-reflection layer in the capping layer and includes transition metals and nitrogen atoms; and a light absorption pattern covering a portion of the capping layer.

PURPOSE: An image processing apparatus and an image processing method corrects the loss and expansion of an object in a rendering. CONSTITUTION: An image receiving unit(10) receives two-dimensional image signal including a background and at least one object. Based on depth information about the object, an image processing unit grasps a hole area shown by the shift of the object. Based on the layer information of the background and the object, the image processing unit performs the inpainting of the hole area.

Abstract:
PURPOSE: A megasonic cleaning method and device are provided to improve a surface washing effect by creating micro-cavities with high power which is offered from a bubbling creating part and to prevent the generation of faults in a pattern which is formed in a substrate. CONSTITUTION: A cleaning object is loaded(S10). A micro cavity for washing the cleaning object is created(S12). Micro cavities which have stable vibration by the cleaning object are only transferred to a loaded space(S14). Micro cavities which have unstable vibration are destroyed or eliminated when the cleaning object is transferred to the loaded space. Second power for maintaining the vibration of the micro cavity is provided(S16). The surface of the cleaning object is washed using micro cavities of the stable vibration(S18).
Abstract:
전압변환회로는 전압측정장치에 있어서, 고전압을 적절하고 안정된 저전압으로 변환시킴으로써 정확한 측정을 위한 것이다. 이를 위하여 고전압에 비례한 출력펄스열을 발생시켜 줌과 동시에 입출력을 상호 절연시켜 주는 전압제어발진회로와 전압제어발진회로로부터 출력된 주파수를 원하는 전압값으로 변환시켜주는 주파수-전압변환회로를 포함한다. 따라서 고전압의 경우에 안정되고 정확한 전압측정을 가능케할 수 있고 또한 오실로스코프의 경우 설치된 프로브에 대한 조건에 관계없이 고전압측정이 가능하므로 프로브를 구비하는 비용을 절감시킬 수 있는 효과가 있다.
