Depositing of functional organic thin films by vacuum evaporation Material evaporation under high or ultra‐high vacuum conditions has been a well known method of thin film coating since nearly a hundred years. Since discovery of semiconducting organics in the 1970s and 1980s, this technology has been increasingly applied to deposit organic molecular compounds. At the moment especially materials for organic LEDs (OLEDs) and for thin‐film solar cells are in the focus of interest. While organics evaporation makes use of advantages of high‐vacuum coating (purity, compatible processing, masking etc.) there are also dedicated demands on process control coming up. The article describes basic requirements, capabilities of present temperature‐controlled evaporation sources, material‐related features, as well as typical applications. 相似文献

Various functional metal-oxide coatings on glass substrate have the possibility to be used for many applications in these days. For keeping the high performance of these applications, it is very important to understand the adsorption property on those coating surfaces. However, there are few reports about such properties of metal-oxide film surface in vacuum state, especially the carbon adsorption property on fluorine-doped tin oxide (SnO2:F) film in vacuum.In this study, we have investigated the chemical state on SnO2:F film in vacuum with XPS analysis. From the results of the SnO2:F film surface analysis, the adsorbed carbon (C1s orbit) on the SnO2:F film surface and the adsorbed carbon dependence of heat treatment in vacuum were observed. Also, it was found that the adsorbed carbon distribution on the SnO2:F film existed after the heat treatment at low temperature in vacuum, uniformly spread in large area with UV light irradiation. Besides, the influence of UV light irradiation with respect to the carbon contents in the SnO2:F film was observed by SIMS analysis. As the result, it was implied that the carbon state in the SnO2:F film remained unchanged under UV light irradiation and the carbon adsorption and desorption occurred only on the surface of the SnO2:F film. 相似文献

For the last decades, both the ophthalmic and the precision optics industries have been relying on vacuum evaporation on the production floor. This particular thin film process is not very suitable for mass production. A major problem in mass production of high quality consumer products is the lack of automatic operation in single chamber evaporation coaters. This article describes a new coating process for lenses which uses both PECVD and sputtering technologies. A new InLine machine equipped with these technologies is presented. This machine meets all requirements with respect to process stability and automation for the respective industry. With its modular design concept, this coating machine can be totally integrated into an InLine factory floor. It can also easily be scaled up or down for a wide range of applications. Given the excellent quality that has been achieved for hardcoat and antireflective coating of plastic eyeglass lenses, similar results can be expected in other thin film applications for a wide range of temperature sensitive substrates in precision optics. 相似文献

Plasma-ion assisted deposition, a newly developed evaporation technique for the production of optical coatings results, in outstanding film properties even at a low substrate temperature. The results of single layer investigations in comparison with conventional evaporation demonstrate the physical effects that improve the film properties. The combination of hard- and anti reflexion coating in one vacuum process for plastic eye glass lenses reduces the production time drastically while the quality of the finished product is secured. The production of ultra stable interference filters for fiber optic communication applications demonstrates the superior ability of this technology. 相似文献

Coatings for Life Science Thin film technologies being well known from semiconductor industry and corresponding technologies for microstructures are successfully used in Life Science (medical technology, pharmaceutical research or biology). These technologies are the base of the complex and miniaturized life science products. Life Science is a strongly growing part of microsystems technology enabling innovations like the cochlear implant replacing the human ear or new products like the retina implant, the latter being shortly before market entrance. Since 1960 the use of plastic material in this field grew rapidly and still today it is a growing market for plastic material manufacturers. The reasons are cheap production and easy way to sterilize plastic material disposables.Unfortunately in many cases plastic materials do not possess the desired surface properties. But an additional (functional) coating may lead to the necessary properties. Low pressure vacuum technology as a sub group of vacuum coating technology is well suited for this surface modification. Normally process temperatures are only between 20 °C – 60 °C. Ceramic and metal based products in Life Science can be modified, too. There is a wide range of coating applications e.g. diamond like coatings on stents leading to decreased thrombus formation. In this overview basics of vacuum coating technology and plasma technology are described and examplarily some aspects and applications in Life Science are shown. 相似文献
