High-voltage power supply in thin-film thickness measurement

High-voltage power supply is a common electronic component in the electronics industry, widely used. It has the characteristics of output high voltage, low current, rapid response speed, high stability, and is widely used in measurement, testing, and analysis. Among them, in the field of thin-film thickness measurement, the application of high-voltage power supply is particularly important.
Thin film refers to a layer of material with a thickness that is thin. It is widely used in the fields of electronics, semi-conductor, optoelectronics, photonics, fiberoptics, medicine, food, etc. The thickness measurement of thin film is a very important work, which directly relates to the quality and performance of the thin film. In the field of thin film thickness measurement, traditional methods such as mechanical or electromagnetic measurement have some error and uncertainty.
The application of high-voltage power supply in thin-film thickness measurement mainly consists of two ways: high-voltage discharge method and resistance measurement method. The high-voltage discharge method is to accelerate the thin film to a very high speed and use high-voltage power supply to discharge, and observe the degree of damage to the thin film to estimate its thickness. This method has the characteristics of fast, accurate, suitable for the measurement of the thickness of various materials. Resistance measurement method is to use high-voltage power supply to put pressure on the thin film, and measure its resistance value, and estimate the thickness of the thin film based on the variation of the resistance value. This method is suitable for the thickness measurement of some materials, such as silicon wafers, aluminum foil, etc.
The application of high-voltage power supply in thin-film thickness measurement has the following advantages:

High accuracy: High-voltage power supply can output high voltage, low current, rapid response speed, and can obtain accurate measurement results in a short time.

High reliability: High-voltage power supply has high stability and accuracy, and can work continuously for a long time to ensure the reliability of the measurement.

Wide application range: High-voltage power supply can be applied to the measurement of the thickness of various materials of thin film, including metals, non-metals, organic materials, etc.

High safety: High-voltage power supply uses the high-voltage discharge or resistance measurement method, which can effectively ensure the safety of the measurement.
In summary, the application of high-voltage power supply in thin-film thickness measurement has important significance. It not only improves the accuracy and reliability of the thin-film thickness measurement, but also expands the application range of the thin-film thickness measurement, and plays an important role in improving the quality and performance of the thin film.
