Abstract: PURPOSE: A multi-surface reflection prism and an optical pickup device are provided to lower the height of an optical system without reducing light beams regardless of wavelength to use, thereby realizing a compact optical pickup device. CONSTITUTION: An optical pickup device employing a multi-surface reflection prism includes a light generating/detecting part for generating and projecting a light beam and receiving and detecting the light beam reflected against a recording surface of a recording medium, an objective lens(30) for focusing the light beam projected from the light generating/detecting part to form a light spot on the recording surface of the recording medium, an actuator(31) for driving the objective lens toward the focussing and/or track direction, and a multi-surface prism(20) formed of a single body with a plurality of surfaces, the multi-surface prism reduces the size of the light beam in the height direction by using angular differences between the reflection surfaces, guides the waves of the light beam in the horizontal direction perpendicular to the height direction, and reflects the waves on the reflection surfaces by an angle smaller than 25° with respect to the horizontal direction.

Abstract: PURPOSE: An SIM(Solid Immersion Mirror) type objective lens is provided to form the first transmission surface as a convex curve on an optical axis and a concave curve in an SIM structure, thereby implementing a high aperture and having a working distance capable of performing a far field recording/reproducing. CONSTITUTION: The first transmission surface(51) is composed of a convex curve(51a) and a concave curve(51b) on an optical axis. The second transmission surface(53) located opposite to the first transmission surface transmits an incident light. The first reflective surface(55) formed around the second transmission surface reflects the incident light. The second reflective surface(57) formed around the first transmission surface(51) reflects the incident light. The convex curve of the first transmission surface focuses a light incident on a radical axis from a light source. The concave curve formed around the convex curve emits a light incident to an external side of the convex curve.

Abstract: PURPOSE: An apparatus is provided to reject a failed glass substrate from a process line by detecting a crack in advance. CONSTITUTION: Transfer robot(20) loads a substrate(1) from a cassette(30) to a loading gate(12). Light emitting cells(41,43) of reflection type optical sensor(40) placed around a loading gate radiate beam to coming substrate. Light receiving cells(42,44) detect a reflective light and provide detected signal to a controller(13). If a radiated light passes directly through a substrate along a line(b) without reflection, optical sensors determine that a crack is occurred on a substrate, and provide a fault signal to a controller. In this case, a controller provides an alarm to an operator to take out a fault substrate.

Abstract: 본 발명에 따른 커패시터 제조방법은 MFS 혹은 MFIS 구조의 커패시터를 제조함에 있어서, 기판 위에 희생층 박막을 형성하는 단계; 상기 희생층 박막 위에 강유전체 박막을 형성하여, 희생층의 물질이 강유전체 물질로 확산 및 흡수되도록 하는 단계; 및 상기 강유전체 박막 위에 전극을 형성하는 단계를 포함하는 점에 그 특징이 있다.
이와 같은 본 발명에 의하면, 기판과 강유전체 사이에 산화물로 된 희생층 박막이 존재하므로 종래와 같은 이물질의 생성이 억제되며, 강유전체 박막의 증착도중에 확산작용에 의해 상기 희생층이 강유전체 박막에 흡수되므로 MFS 구조를 이루게 된다. 만일, 이 희생층의 흡수가 완전치 못하여 이 층이 잔존하게 될 경우는 MFS 구조가 아닌 MFIS 구조가 되지만, 잔존 희생층(MFIS 구조의 절연층에 해당)의 두께가 초기에 비해 얇게 되므로 MFIS 구조의 커패시터에서의 절연층의 두께를 감소시키는 결과가 되어 MFIS 구조의 커패시터의 특성을 향상시키는 효과를 얻을 수 있다.-

Abstract: 본 발명에 따른 커패시터 제조방법은 MFS 혹은 MFIS 구조의 커패시터를 제조함에 있어서, 기판 위에 희생층 박막을 형성하는 단계; 상기 희생층 박막 위에 강유전체 박막을 형성하여, 희생층의 물질이 강유전체 물질로 확산 및 흡수되도록 하는 단계; 및 상기 강유전체 박막 위에 전극을 형성하는 단계를 포함하는 점에 그 특징이 있다.
이와 같은 본 발명에 의하면, 기판과 강유전체 사이에 산화물로 된 희생층 박막이 존재하므로 종래와 같은 이물질의 생성이 억제되며, 강유전체 박막의 증착도중에 확산작용에 의해 상기 희생층이 강유전체 박막에 흡수되므로 MFS 구조를 이루게 된다. 만일, 이 희생층의 흡수가 완전치 못하여 이 층이 잔존하게 될 경우는 MFS 구조가 아닌 MFIS 구조가 되지만, 잔존 희생층(MFIS 구조의 절연층에 해당)의 두께가 초기에 비해 얇게 되므로 MFIS 구조의 커패시터에서의 절연층의 두께를 감소시키는 결과가 되어 MFIS 구조의 커패시터의 특성을 향상시키는 효과를 얻을 수 있다.
