TECHNICAL FIELD The present invention relates to a sputtering apparatus, and more particularly, to a continuous vacuum roll-to-roll sputtering apparatus.

플렉서블 코팅을 위해 현재에는 기존의 인라인 스퍼터링 글래스(Inline Sputtering Glass) 코팅 방식의 캐소드를 사용한다. 그런데, 기존 롤투롤 방식(코팅존)은 원호 형태의 메인 드럼을 사용하고 있고, 이에 비해 타겟은 평면 형태로서고정된 드럼 및 고정된 타겟 위치에 따라 일정한 방향으로 입자가 성장하는 형태를 갖게 된다. 한편, 한국공개특허 제10-2010-0065624호에는 기판 양면 증착을 위한 롤-투-롤 스퍼터 시스템이 제시되어 있다.
For flexible coating, the current inline sputtering glass coating method uses a cathode. However, the conventional roll-to-roll method (coating zone) uses an arc-shaped main drum, whereas the target has a shape in which particles grow in a predetermined direction according to a fixed drum and a fixed target position as a planar shape. Meanwhile, Korean Laid-Open Patent Publication No. 10-2010-0065624 discloses a roll-to-roll sputter system for double-sided deposition of a substrate.

However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various forms, and only the embodiments are intended to complete the disclosure of the present invention and to those skilled in the art. It is provided for complete information.

도 1은 종래의 캐소드 및 그에 따른 박막 증착 형상을 도시한 개략도이고, 도 2는 본 발명에 따른 캐소드 및 그에 따른 박막 증착 형상을 도시한 개략도이다.1 is a schematic diagram illustrating a conventional cathode and a thin film deposition shape, and FIG. 2 is a schematic diagram illustrating a cathode and a thin film deposition shape according to the present invention.

도 1(a)에 도시된 바와 같이 캐소드(40) 상에 마그넷(30)이 마련되고 그 상부에 타겟이 마련된다. 이때, 캐소드(40)은 상부면 및 하부면이 평탄하게 마련된다. 이를 이용하여 평판 기판(10) 상에 박막을 증착하는 경우 박막은 캐소드(40)의 고정된 위치에 따라 일정한 방향으로 성장하게 된다. 또한, 도 1(b)에 도시된 바와 같이 플렉서블 기판(10) 상에 박막을 증착하는 경우에도 복수의 캐소드(40)가 플렉서블 기판(10)의 휨 각도에 따라 소정 각도로 기울어져 배치된다. 이때, 캐소드(40)는 상부면 및 하부면이 평탄하고, 플렉서블 기판(10)의 휨 각도와 대향되도록 캐소드(40)가 기울어져 배치된다. 이 경우에도 박막은 캐소드(40)의 고정된 위치에 따라 일정한 방향으로 성장하게 된다.As shown in FIG. 1A, a magnet 30 is provided on the cathode 40, and a target is provided thereon. At this time, the cathode 40 has a flat upper surface and lower surface. When the thin film is deposited on the flat substrate 10 using the thin film, the thin film grows in a predetermined direction according to the fixed position of the cathode 40. In addition, as shown in FIG. 1B, when the thin film is deposited on the flexible substrate 10, the plurality of cathodes 40 are inclined at a predetermined angle according to the bending angle of the flexible substrate 10. At this time, the cathode 40 has a flat top and bottom surfaces, and the cathode 40 is disposed to be inclined so as to face the bending angle of the flexible substrate 10. Even in this case, the thin film grows in a constant direction according to the fixed position of the cathode 40.

그러나, 도 2(a)에 도시된 바와 같이 본 발명에 따른 캐소드(50)는 하부면이 평탄하고, 상부면이 소정의 기울기를 가지고 마련된다. 이때, 상부면의 기울기는 박막의 증착 방향에 따라 조절할 수 있다. 또한, 캐소드(50)의 기울기는 조절 가능하다. 이를 이용하여 평판 기판(10) 상에 박막을 증착하는 경우 박막은 입자의 크기 및 성장 방향을 조절할 수 있어 박막의 표면 특성을 개선할 수 있고, 그에 따라 박막의 품질을 향상시킬 수 있다. 예를 들어, 입자의 크기를 고/저/고, 저/고/저. 저/고, 고/저 등 다양하게 조절하여 형성할 수 있다. 이는 도 2(b)에 도시된 플렉서블 기판(10) 상에 박막을 증착할 때에도 동일하게 적용할 수 있고, 플렉서블 기판(10) 상에서도 입자의 크기 및 성장 방향을 조절할 수 있다.
However, as shown in FIG. 2A, the cathode 50 according to the present invention is provided with a flat lower surface and an upper surface with a predetermined slope. At this time, the inclination of the upper surface may be adjusted according to the deposition direction of the thin film. In addition, the inclination of the cathode 50 is adjustable. When the thin film is deposited on the flat substrate 10 using the thin film, the size and growth direction of the thin film can be controlled to improve the surface characteristics of the thin film, thereby improving the quality of the thin film. For example, change the size of the particles to high / low / high, low / high / low. It can be formed by various adjustments such as low / high, high / low. The same applies to depositing a thin film on the flexible substrate 10 shown in FIG. 2 (b), and can also control the size and growth direction of particles on the flexible substrate 10.
