EVAPORATION MATERIALS APPLICATION
Vacuum evaporation, a process involving the vaporization of coating material under vacuum conditions and its condensation on a substrate surface to form a film, is an early and widely used vapor deposition technology. It offers advantages such as a simple film-forming method, high film purity and density, and unique film structure and performance.
Evaporation materials, as a critical base material industry in the electronic information sector, are at the forefront of the electronic industry chain. High-purity evaporation materials are extensively used in various fields, including high-efficiency thin-film CIGS solar cell modules, OLED lighting components, optical components, light-emitting diodes, and flat panel displays.
The predominant preparation methods for sputtering targets currently include the casting process and powder metallurgy process.
EVAPORATION MATERIALS SELECTION GUIDE
When selecting the optimal evaporation material for an application, several key factors must be considered, including: 1. The required refractive index; 2. The desired coverage area; 3. The shape and size of the evaporation materials; 4. The permissibility of radioactive vapors such as thorium fluoride. Additionally, other considerations should be factored into the selection of evaporation materials:
In addition, some other factors should be considered when choosing evaporation materials:
Application effect test
The cost of the evaporation material is relatively minor when compared to the overall value of the optical component or the time invested in coating processes. Consequently, it is imperative that the evaporation material is compatible with vacuum systems. Each batch of evaporation materials should undergo examination for some or all of the following parameters:
1. Evaporation ease;
2. Residual gas monitoring;
3. Measurement of the refractive index in a thin film state;
And the distribution and composition of the remaining material components. Conducting these tests necessitates an evaporation chamber equipped with electrical resistance and electron beam sources, cryopumps, optical monitoring systems, and spectrometers.
Chemical Purity
Typically, suppliers of evaporation materials specify the overall purity, often denoted as several ‘nines’ (e.g., 99.999%). However, a more practical measure of purity is the maximum permissible amount of each specific impurity. For instance, in a metal fluoride, the oxide content can significantly influence the film’s refractive index.
Process
Suppliers of evaporation materials are expected to furnish users with comprehensive developmental information about the materials. This approach empowers optical coating companies to sustain a contemporary technological standard and remain competitive in the industry.
As PVD technology evolves in response to the dynamic needs of coating processes, the consistency and volume of evaporation materials become crucial. Through careful selection of both evaporation materials and their manufacturers, it is possible to mitigate uncertainties in the coating process.
