The 0690012020 application field is the application of phase shift optical diagnostics. This diagnostic is widely used in the semiconductor industry, among other applications. It is a technique which measures the phase shift of the light passing through a sample using an ellipsometer. This technique is used for quantifying thin film thickness, optical constants, and optical properties. Additionally, it provides a non-destructive and non-invasive approach for characterizing the optical properties of a sample.

The working principle of the 0690012020 application field is similar to traditional ellipsometry, but with an added layer of sophistication and accuracy. The purpose is to measure the phase shift of light after leaving the sample surface to characterize the optical properties of a material or thin film. To accomplish this, an incident light is sent onto the sample and then measured in terms of its refractive index, reflectance, polarized light, or some combination of these parameters.

To measure the phase shift of a material, the light is split into a polarized beam and then sent into the sample. This beam is then subjected to three sequential measurements, each one providing a measure of the sample\'s optical properties. During the first measurement, the optical constants of the sample are detected. During the second measurement, the optical parameters of the sample such as reflectance, thickness, and refractive index are measured. Finally, during the third measurement, the degree of phase shift that has occurred in the sample is measured.

Using the results of these three measurements, the properties of the sample and the degree of changes that have occurred are calculated. This calculation allows researchers to identify defects in a material as well as changes in the optical properties of the sample due to environmental or light processing. It also provides an accurate assessment of thin film properties such as refractive index, optical constants, and thickness.

In addition to the traditional application of 0690012020, this technology can also be employed to detect very small changes within a material or thin film. This can be particularly important in industry, as it can detect microscopic changes that are not visible with the naked eye. The small changes that this technique can detect can be used to identify changes that occur in materials due to exposure to extreme temperatures, as well as to accurately monitor the current state of the materials in the manufacturing process.

In conclusion, the 0690012020 application field provides for accurate measurement and detection of the optical properties of a sample, including the degree of phase shift that has occurred. This technology is widely used in the semiconductor industry as well as other applications such as measuring thin film properties. It is a non-destructive and non-invasive technique which offers an accurate and precise assessment of a sample\'s properties. Additionally, it can be used to detect very small changes in a sample due to environmental or light processing.
