이하 상기와 같이 구성되는 박막코팅장치(200)를 이용하여 투습방지막이 구비된 기판을 제조하는 방법을 첨부된 도 5를 참조하여 설명한다.Hereinafter, a method of manufacturing a substrate having a moisture barrier film using the thin film coating apparatus 200 configured as described above will be described with reference to FIG. 5.

도 5에는 본 발명에 의한 투습방지막이 구비된 기판의 제조방법을 나타낸 순서도가 도시되어 있다.5 is a flowchart illustrating a method of manufacturing a substrate provided with a moisture barrier film according to the present invention.

도면과 같이, 투습방지막(140)이 구비된 기판을 제조하는 방법은, 크게 폴리머로 이루어진 투명 모재(120)의 표면을 이온빔을 이용하여 전처리하는 전처리단계(S100)와, 전처리된 모재(120)의 표면에 투습방지막(140)을 형성하는 투습방지막 형성단계(S200)로 이루어진다.As shown in the drawing, a method of manufacturing a substrate provided with the moisture barrier film 140 includes a pretreatment step (S100) of pretreating the surface of the transparent base material 120 largely made of polymer using an ion beam, and the pretreated base material 120. It consists of a moisture barrier film forming step (S200) to form a moisture barrier film 140 on the surface of the.

상기 전처리단계(S100)는 설치지그(220)의 하면에 모재(120)를 설치한 후 상기 저진공펌프와 고진공펌프를 이용하여 진공챔버(210) 내부의 진공도를 1x10-5torr 로 맞춘 다음 유지하게 된다.In the pretreatment step (S100), after installing the base material 120 on the lower surface of the installation jig 220, the vacuum degree inside the vacuum chamber 210 is adjusted to 1x10 -5 torr using the low vacuum pump and the high vacuum pump, and then maintained. Done.

이런 상태에서 상기 이온빔장치(260)를 작동시켜 상기 모재(120) 상에 존재하는 흡착가스 입자들과 오염물질을 제거하게 된다.In this state, the ion beam device 260 is operated to remove the adsorbed gas particles and the contaminants present on the base material 120.

즉, 본 발명의 실시예에서 상기 이온빔장치(260)는 필라멘트로부터 열전자를 방출하여 플라즈마를 발생시키고 플라즈마에 존재하는 이온들을 가속시켜 방출하는 엔드홀(End-Hall) 방식이 적용되었다.That is, in the embodiment of the present invention, the ion beam device 260 generates a plasma by emitting hot electrons from the filament, and an end-hole method for accelerating and emitting ions present in the plasma is applied.

보다 상세하게는 상기 진공챔버(210) 내부에 혼합가스(Ar)을 주입하여 5x10-5torr 내지 5x10-4torr의 진공도를 유지하였고, 필라멘트의 파워는 약 400W(20A x 20V), 이온빔장치(260)의 파워는 180W (2A x 90V)로 설정하여 3분 내지 5분 실시하였다.More specifically, the mixed gas (Ar) was injected into the vacuum chamber 210 to maintain a vacuum degree of 5x10 -5 torr to 5x10 -4 torr, and the power of the filament was about 400W (20A x 20V) and the ion beam device ( The power of 260 was set to 180 W (2A x 90V) and carried out for 3 to 5 minutes.

상기와 같은 과정에 따라 전처리단계(S100)가 완료되면, 상기 투습방지막형성단계(S200)가 실시된다.When the pretreatment step S100 is completed according to the above process, the moisture barrier film forming step S200 is performed.

상기 투습방지막형성단계(S200)는 금속박막(142)을 형성하는 박막형성과정(S220)과, 상기 금속박막(142) 하면에 실리콘계화합물(144)을 형성하는 화합물형성과정(S240)이 순차적으로 실시되어 투습방지막(140)이 형성되는 과정이다.In the moisture barrier film forming step (S200), a thin film forming process (S220) for forming the metal thin film 142 and a compound forming process (S240) for forming a silicon compound 144 on the lower surface of the metal thin film 142 are sequentially performed. It is the process of forming the moisture barrier film 140 is performed.

즉, 상기 박막형성과정(S220)은 상기 모재(120)에 스퍼터링법(Sputtering) 또는 진공증착법(Thermal Evaporation)으로 금속박막(142)을 형성하는 과정이며, 상기 화합물형성과정(S240)은 금속박막(142) 하면에 플라즈마중합법(Plasma Polymerization)으로 실리콘계화합물(144)을 형성하는 과정이다.That is, the thin film forming process (S220) is a process of forming a metal thin film 142 on the base material 120 by sputtering or thermal evaporation, and the compound forming process (S240) is a metal thin film. A process of forming the silicon compound 144 on the bottom surface by plasma polymerization is performed.

상기 박막형성과정(S220)에서 형성되는 금속박막(142)은 실리콘(Si), 은(Ag), 티타늄(Ti), 알루미늄(Al), 저매늄(Ge), 크롬(Cr), 니켈(Ni), 인듐(In), 주석(Sn) 및 이들을 혼합한 합금 물질을 1nm 내지 30nm의 두께로 증착시키는 과정이다.The metal thin film 142 formed in the thin film formation process S220 may be formed of silicon (Si), silver (Ag), titanium (Ti), aluminum (Al), low maenyum (Ge), chromium (Cr), and nickel (Ni). ), Indium (In), tin (Sn) and an alloy material mixed with them are deposited to a thickness of 1nm to 30nm.

그리고, 상기 화합물형성과정(S240)은 상기 금속박막(142) 하면에 플라즈마 중합 공정(Plasma Polymerization)을 이용하여 투습도를 조절할 수 있는 실리콘계화합물(144)을 증착시키는 과정이다.In addition, the compound forming process (S240) is a process of depositing a silicon compound 144 that can control the moisture permeability using a plasma polymerization process (Plasma Polymerization) on the lower surface of the metal thin film (142).

이를 위해 상기 화합물형성과정(S240)에서는 진공챔버(210) 내부에 HMDSO 기체를 주입하였으며, 상기 진공챔버(210) 내부의 바람직한 진공도를 맞추기 위해 아르곤(Ar), 캐리어 가스 및 반응가스(산소(O2), 질소(N2), 또는 산소 질소 혼합 가스)를 주입하였다.To this end, in the compound formation process (S240), HMDSO gas was injected into the vacuum chamber 210, and argon (Ar), a carrier gas, and a reaction gas (oxygen (O) were used to meet a desired degree of vacuum in the vacuum chamber 210. 2 ), nitrogen (N 2 ), or oxygen nitrogen mixed gas) was injected.

상기한 조건에서 상기 알에프전원수단(230)에 전원을 인가하여 상기 금속박막(142) 하면에 실리콘계화합물(144)이 증착되도록 하였다.The silicon-based compound 144 was deposited on the bottom surface of the metal thin film 142 by applying power to the RF power supply unit 230 under the above conditions.

상기 실리콘계화합물(144)은 Tri-methyl과 결합하고 있는 실리콘(Si) 원자가 플라즈마 에너지에 의해 파괴되어 SixOy 와 같은 단량체(Monomer)들이 형성되고, 이렇게 분해된 단량체들이 플라즈마 에너지에 의해 다시 반응기체 (산소 또는 질소) 들과 중합되는 중합 반응이 금속박막(142) 표면에서 발생하여 SiOX, SiOxNy, SiCxHyOz 중 어느 하나로 로 이루어진 실리콘계화합물(144)이 피복되는 것이다.In the silicon compound 144, silicon (Si) atoms bonded to trimethyl are destroyed by plasma energy to form monomers such as Si x O y, and the decomposed monomers are reacted again by plasma energy. A polymerization reaction that polymerizes with the gases (oxygen or nitrogen) occurs on the surface of the metal thin film 142 and thus SiO X , SiO x N y , SiC x H y O z The silicon compound 144 made of any one is coated.

그리고, 상기 실리콘계화합물(144)은 RF 전력이 클수록, 진공챔버(210) 내에 HMDSO 기체량이 많을수록 증착속도가 증가되며, 상기 투습방지막형성단계(S200)는 전술한 바와 같이 다수회 반복 실시가 가능하다.In addition, as the silicon compound 144 has a larger RF power and a larger amount of HMDSO gas in the vacuum chamber 210, the deposition rate increases, and the moisture barrier film forming step S200 may be repeated a plurality of times as described above. .

이하 상기와 같은 제조방법에 따라 실시된 본 발명의 실시예를 첨부된 도 6 및 도 7을 참조하여 설명한다.Hereinafter, an embodiment of the present invention carried out according to the above-described manufacturing method will be described with reference to FIGS. 6 and 7.

[실시예 2] 및 [실시예 3]과 같은 조건에서 형성된 금속박막과 실리콘계화합물을 포함하는 투습방지막(140)의 표면을 전자 현미경으로 관찰한 결과, [실시예 1]에서 나타났던 산화실리콘 박막 입자 조대화에 따른 결함이 전혀 발생되지 않았다.[Example 2] and [Example 3], the surface of the moisture barrier film 140 containing the metal thin film and the silicon-based compound formed under the same conditions as the electron microscope, as a result of the silicon oxide thin film appeared in Example 1 No defects due to grain coarsening occurred.

그리고, [실시예 2],[실시예 3]에 따라 제조된 기판(100)은 10-2g/m2/day의 투습도를 나타냈으며, [실시예 3]의 조건으로 제조된 기판(100)은 실험 조건에 따라 1×10-3g/m2/day ~ 5×10-3g/m2/day의 투습도 범위를 나타내었다.In addition, the substrate 100 manufactured according to [Example 2] and [Example 3] exhibited a moisture permeability of 10 −2 g / m 2 / day, and the substrate 100 manufactured under the conditions of [Example 3] ) Shows a water vapor transmission range of 1 × 10 −3 g / m 2 / day to 5 × 10 −3 g / m 2 / day depending on the experimental conditions.

Therefore, when the thin film formation process and the compound formation process are sequentially performed a plurality of times, the moisture permeability is obviously lowered when the moisture barrier layer 140 is laminated in multiple layers.

이러한 본 발명의 범위는 상기에서 예시한 실시예에 한정되지 않고, 상기와 같은 기술범위 안에서 당업계의 통상의 기술자에게 있어서는 본 발명을 기초로 하는 다른 많은 변형이 가능할 것이다.The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

따라서, 투습방지막은 가시광선 투과도에 큰 영향을 미치지 않으면서 투습도나 투산소도를 감소시킬 수 있는 이점이 있다.Therefore, the moisture barrier film has an advantage of reducing the moisture permeability and oxygen permeability without significantly affecting the visible light transmittance.
