一种扩散膜涂层的涂覆方法 A method of coating a diffusion membrane coatings

技术领域 FIELD

[0001] 本发明涉及平板显示技术中光学薄膜领域,特别涉及一种用于平板显示技术中在基板上涂覆扩散膜涂层的涂覆方法路线。 [0001] The present invention relates to an optical film in flat panel display technology, and more particularly relates to a coating method for a flat panel display line art on a substrate coated with a diffusion membrane coatings.

背景技术 Background technique

[0002] 现代高科技的三大重点领域是材料、能源和信息科学。 [0002] Modern high-tech three key areas are materials, energy and information science. 它们对物质材料不断提出新的性能要求。 They have made new performance requirements of materiality. 近几年来,薄膜技术随着高科技的发展有了突飞猛进的进展。 In recent years, thin-film technology with high-tech development has been rapid progress. 由于镀膜技术、薄膜材料、表面物理三者的相互推进和结合,使得薄膜技术成为一门综合性的应用科学,是今后工业发展的新重点。 Due to combine with each other to promote and coating technology, thin film materials, surface physics of the three, makes thin-film technology to become a comprehensive applied science, is the new focus of future industrial development. 在一些发达国家,薄膜技术被全方位推广应用。 It is a full range of application in some developed countries, thin-film technology. 除了发展光学薄膜集成电路薄膜、液晶显示膜、磁盘、光盘薄膜外,还大量生产刀具硬质膜、太阳能用薄膜、气敏元件薄膜、塑料金属化制品、建筑玻璃膜制品、各种装饰膜和卷镀薄膜产品等。 In addition to the development of optical thin film integrated circuits, liquid crystal display film outside, magnetic disks, optical films, mass production of tools hard film, solar film, the gas sensor film, metalized plastic products, architectural glass film products, and a variety of decorative films volume plated film products. 薄膜之所以成为研究的热点,并且具有广阔的应用前景,是与薄膜材料的以下特点密切相关: The reason why the film has become a hot research and has broad prospects, is closely related to the following characteristics of thin film materials:

许多情况下,材料功能的发挥和作用发生在材料表面。 In many cases, the material play a role and function occurs on the material surface. 如化学催化、光学反射、场致发射、热电子逸出等物理化学现象。 The chemical catalysis, optical reflection, field emission, the electron emitting heat and other physical and chemical phenomena. 使用功能薄膜材料比使用体块功能材料不仅保护资源,而且降低成本。 Using the function than the bulk film material not only to protect the functional material resources and reduce costs. 薄膜材料往往具有一些其块体材料所不具备的性能。 The film material tend to have some of its bulk materials do not have properties. 这是因为薄膜材料容易形成细晶、非晶状态,薄膜材料容易处于亚稳态,薄膜往往偏离化学计量比,特殊的材料表面能态等。 This is because the material is easily formed thin fine crystalline, amorphous, thin film material easily in a metastable state, the film tends to deviate from the stoichiometric ratio, specific surface energy states and the like.

[0003] 镀膜方法有湿法和干法。 [0003] Coating methods are wet and dry. 湿法包括电镀和化学镀。 The wet process includes electroplating and electroless plating. 干法包括化学气相沉积法(CVD)和物理气相沉积法(PVD)。 Dry process comprising chemical vapor deposition (CVD) and physical vapor deposition (PVD). 薄膜的制备常采用PVD法和CVD法。 Preparation of the film is often used PVD and CVD. PVD法是在真空或超真空下将金属加热气化,通过气态原子之间或与作保护气的惰性原子之间碰撞并被捕集于基材上来制备薄膜。 A PVD method or ultra-high vacuum in a vacuum heating the metal vaporized by between atoms or with an inert gas as protective and collisions between gas atoms trapped onto a substrate film was prepared. CVD法是利用气相物质的热分解、热合成或化学传输等在基底材料上生成固态沉积的膜层。 Thermal decomposition CVD method using a gas material, heat transfer, or chemical synthesis and the like form a solid layer deposited on the base material. 一般沉积温度高达IOOOe左右,有些材料经受不住高温,则可采用等离子体化学气相沉积技术。 The deposition temperature is generally as high as IOOOe, some materials withstand high temperatures, it can be a plasma chemical vapor deposition techniques. 它是用气体放电等离子体来促进化学反应,这样可以在较低的温度下操作(500— 600e)。 It is a gas discharge plasma promote chemical reactions, which can operate (500- 600e) at a lower temperature. CVD法包括金属有机物的化学气相沉积(M0CVD)和金属有机物等离子体化学气相沉积(M0PCVD)等。 CVD method includes a metal organic chemical vapor deposition (M0CVD) and metal organic chemical vapor deposition plasma (M0PCVD) and the like. 近年来溶胶-凝胶法镀膜受到人们的广泛关注,它具有生产成本相对较低、镀膜效率高、镀膜均匀性好等优点。 In recent years sol - gel film received extensive attention, which has relatively low production costs, high coating efficiency and good film uniformity. 其应用领域的研究非常活跃,在新材料的研制、材料改性与拓宽用途方面也发挥着重要作用。 Research fields of application are very active in the development, modification and broaden the use of the material aspects of new materials also plays an important role.

[0004] 薄膜涂覆是一种重要的现代表面工程技术。 [0004] The film-coated surface is an important modern engineering. 涂覆层的化学成分、组织结构可以和基体材料完全不同。 Chemical composition of the coating layer, the organizational structure and the base material may be entirely different. 涂覆薄膜厚度非常小而且尺寸精度要求非常高,可以起到3方面的作用:优化表面性能、进行微细加工和产生新的功能材料。 The coating film thickness is very small and the dimensional precision is very high, may act in three areas: optimized surface properties, fine processing and generation of new functional materials. 但是薄膜在涂覆过程中往往经常会出现褶皱,条纹,和气泡等缺陷。 However, the film tends to wrinkle often, stripes, bubbles, and other defects occur in the coating process. 薄膜涂覆加工工艺过程对薄膜成膜的质量有着重要的影响,然而大多数研究人员主要是研究薄膜涂料的制备及成型方法,而薄膜的涂覆的加工工艺路线研究较少,因此对薄膜涂层的完整涂覆方法的研究显得尤其重要。 Thin film coating has a machining process on the quality of thin film formation is important influence, however, most researchers mainly prepared coating film forming method and research, and less of the coated film processing line studies, so the film coating complete study of layer coating method is particularly important.

[0005] 本发明方法就是针对目前在薄膜的涂覆过程中容易出现一些缺陷,在光学薄膜的涂覆工艺过程中还没有形成一个良好的完整涂覆工艺加工方法,提出了一种在基片上涂覆一种扩散膜涂层的涂覆方法。 [0005] The method of the present invention addresses the current prone to some defects in the thin film coating process, have not formed a good coating process complete processing method in an optical film during the coating process, there is proposed a substrate on A coated with a diffusion coating process of the coating film.

发明内容 SUMMARY
