Title: 최적의 굴절율로서 향상된 성능을 갖는 광흡수 무반사층
IPC: G03F7/004

Abstract: 본 발명은 반도체 산업에서 이용되는 포토레지스트 물질 용으로서 스윙 커브 진폭이 감소된 광흡수성 정상부 무반사층으로 이루어진다.  코팅은 반드시 국한되는 것은 아니지만 물이 이용될 수 있다.  물을 이용한 코팅의 장점은 소프트베이크 포토레지스트에 혼합하는 일 없이 적용될 수 있기 때문에 이용하기에 편리하며, 현상 단계에서 제거됨으로써, 공정의 복잡성은 최소한으로 증가된다.  기존의 비 흡수성 무반사 코팅과 관련한 단점은 최적의 스윙 커브 감소가 단지 매우 낮은 굴절율에서만 달성된다는 것이다.  염료 코팅의 장점은 a) 염료가 세심하게 선택되었다면 정상부 코트의 굴절율이 이상 분산 효과를 이용함으로써 추가적으로 낮출 수 있다는 것이며, b) 정상부 코트의 높은 굴절율에서 최적의 스윙 커브 감소를 달성할 수 있다는 것이다.  이러한 2가지 효과의 결합으로서 본 발명은 스윙 커브의 감소를 이론적으로 최소한의 값에 근접시켰고, 기존의 무반사 정상부 코트에 대하여 실질적으로 개선시켰음을 증명하였다.

Abstract: PURPOSE: A method is provided to fabricate a high aspect ratio hole without the necessity of an additional process required at using a reactive ion etching process. CONSTITUTION: The method for fabricating a high aspect ratio hole in a semiconductor structure comprises the steps of: providing the semiconductor structure, wherein the semiconductor structure comprises at least one semiconductor substrate (10) or wafer, which has a patterned region having a vertical side wall on at least one of both surfaces thereof; depositing a dielectric layer on the semiconductor surface having the patterned region; forming a thin film layer for making a structure on the dielectric layer be plane; etching back the planar thin film layer and the dielectric layer until the patterned region is exposed; and forming a hole by removing the patterned region, wherein ration of a height to a width of the hole is over 2 and the hole has a vertical side wall.

Abstract: PURPOSE: A liquid drop detecting method is provided to induce the light radiated from a radiation piece into a glass plate and to sense the existence of the liquid drops attached on the glass plate by detecting the light totally reflected inside the glass plate by a light receiving element. CONSTITUTION: The device is composed of:a radiation piece radiating the light of 700-780 nm of wave length; a glass plate to induce the light radiated from the radiation piece; a light receiving element to detect the light totally reflected from the inner side of the glass plate.; Herein, the device used the light having 700-780 nm of wave length as a detection light of the liquid drop detecting device applied for a vehicle so that the detection light is not unpleasant to the eyes of a driver and the degree absorbed at the glass or light shield part. Therefore, the intensity of the light approaching to the light receiving piece and the sensitivity can be improved.
