With the continuous advancement of my country's scientific and technological level, the electronic information industry, energy saving and environmental protection industry, aerospace industry and other fields have continuously increased the requirements for thin film technology, especially optical thin film technology, which is constantly expanding in the space field. This technology plays an important role in promoting the development of many high-tech industries, so what is thin film technology? What is the development prospect of thin film technology?


 

1. What is thin film technology

Thin-film technology, derived from electronics, is a method of making miniaturized electronic circuits by vapor-depositing a layer of components onto an insulating substrate. Using thin-film technology, the achievable structure is small and thick-film technology. In the field of microelectronics, conductor circuits and even elements such as resistors can be added by vapor deposition in one workflow.

Thin-film technology has been widely used in various fields such as electronic components, integrated optics, electronic technology, infrared technology, laser technology, aerospace technology and optical instruments. They not only become an independent application technology, but also become a material surface modification. And an important means to improve the level of some craftsmanship.

2. What is thin film optical technology?

A class of optical media materials composed of thin layered media that propagate light beams through interfaces. The application of optical films began in the 1930s. In modern times, optical films have been widely used in the fields of optics and optoelectronics to manufacture various optical instruments. From precision and optical equipment, display equipment to optical film applications in daily life; for example, glasses, digital cameras, all kinds of household appliances, or anti-counterfeiting technology on banknotes can all be called optical film technology. extension of application.

3. Advantages of thin film technology

One use of thin-film technology is in semiconductor production, including the development of new photovoltaic cells. Size is critical for semiconductors, especially as consumers expect laptops, mobile phones and other electronic devices to be smaller and thinner. Thin films provide stable surfaces with consistent performance without the need for more traditional coatings. It also greatly reduces material costs as it is further developed with less material.

For optics such as lenses, specially treated windows and mirrors, etc., thin-film technology offers higher performance. Thin layers reduce deformation, save weight, and have the same performance as thicker layers of material. Films can filter light, add insulation or turn lenses into mirrors, as needed. This technology is particularly useful for green building design, where treating windows with film can reduce energy loss and increase building efficiency.

Fourth, the development prospects of thin film technology

The rapid development of thin film technology is mainly due to the progress made in the following four areas:

1. The industrial application field is gradually expanding, and the dosage is increasing rapidly;
2. The progress of new analysis and detection technology;
3. Improved monitoring and control of thin film process;
4. The gradual shaping of the thin film process.

In addition to the above four aspects, it is also closely related to the development of vacuum technology, especially high vacuum and ultra-high vacuum technology, and the progress of surface science. Thin film technology has developed into industrial-scale application materials. Energy, electronic information, and optical engineering are the three major pillars of modern society in terms of material, and the future development prospects are broad.
