FAQ

In modern industrial manufacturing, thin-film technology is widely used in semiconductors, optical devices, decorative coatings, and other fields. The thickness of the thin film directly affects the performance and quality of the product. Therefore, real-time monitoring of film thickness during the coating process is crucial. VPI's R&D engineers will introduce why coating equipment needs to be equipped with a film thickness monitor and explain its working principle, focusing on the applications of the 650MH high-vacuum magnetron sputtering coating machine and the 900M sample preparation coating machine.

In the fields of materials science and engineering, thin film preparation is a critical step. Accurately controlling the thickness of the thin film is essential for ensuring product performance and quality. This article introduces how to estimate film thickness and the specific calculation logic when using a coating machine for sample preparation, helping researchers and engineers improve experimental efficiency and result reliability.

Recently, Vision Precision Instruments was pleased to have the opportunity to install and deploy a high vacuum magnetron dual-target sputtering coater (SD-650MHT) for the School of Chemical Engineering at Changchun University of Technology. We are honored to contribute to the research in material science at Changchun University of Technology.

As a key parameter affecting the quality, thickness uniformity and performance of the film, the sputtering rate is affected by many factors, including target type, vacuum degree, working gas pressure, power supply, magnetic field strength and so on. A thorough understanding of the influence of these factors on the sputtering rate is of great significance for optimizing the process parameters and improving the quality of the film.

In the field of modern materials science and nanotechnology, the sample preparation technology of thin films has become a key research topic. These thin film materials are widely used in electronic devices, optical devices, biosensors, catalysts and other fields. In order to obtain films with excellent properties in various applications, it is essential to select the appropriate target material and use high-performance coating equipment. This article will describe in detail the application of gold (Au), silver (Ag), platinum (Pt), and gold palladium (Au/Pd) targets in VPI's SD-900M model coators and their differences in sample preparation.

The SD-650MHT sputtering coating machine adopts advanced mechanical design and precise control systems, featuring extremely high vacuum levels and stable gas control capabilities. Its core components include a combination of a rotary vacuum pump and a turbomolecular pump, which can quickly achieve an ultimate vacuum of 5×10^-5Pa, ensuring high efficiency and stability during the coating process. Additionally, the instrument is equipped with a metal chamber with a diameter of 260mm and a height of 200mm, allowing for larger sample sizes and meeting various experimental needs.

Today, we are proud to announce the launch of a new cathodoluminescence instrument: a precision instrument designed specifically for the characterization of solid materials such as gems and minerals, aiming to bring more solutions to the field of material science.

Good luck in the Year of the Dragon! May everything go as you wish, and may you enjoy peace of mind and good health!

Happy New Year!!

Merry Christmas from VPI China
