Silicon nitride (Si₃N₄) membrane windows, with their high transmittance, heat resistance, and corrosion stability, have become critical components in synchrotron radiation, TEM, and MEMS devices36. This article provides evidence-based maintenance strategies to extend service life by over 30%.

Silicon nitride (Si₃N₄) thin films exhibit unique physical and chemical properties, making them highly advantageous for various optical applications. Below are several detailed case studies:

Silicon nitride (Si₃N₄) is a material with immense potential, widely used in semiconductor, optical, MEMS (Micro-Electromechanical Systems), and high-temperature/high-frequency applications. As a critical inorganic ceramic material, silicon nitride thin films possess excellent mechanical strength, chemical stability, and high-temperature resistance, making them irreplaceable in many high-precision, high-performance devices.

X-ray windows are specialized thin film materials used in X-ray analysis systems. Their primary function is to allow X-rays to pass through and interact with the sample while isolating the vacuum environment from the sample's atmosphere. X-ray windows are commonly used in X-ray spectroscopy, X-ray imaging, X-ray diffraction (XRD), and other applications. Materials such as silicon nitride (Si₃N₄), beryllium, aluminum, and carbon nanotubes are frequently used for these windows.

TEM windows are thin film materials used in transmission electron microscopes (TEM) to support samples and allow electron beams to pass through for imaging and analysis. The main function of a TEM window is to serve as a supporting membrane for the sample while enabling the electron beam to penetrate for detailed imaging. Common materials used for TEM windows include silicon nitride (Si₃N₄), graphene, and quartz, which are chosen for their high transparency to electron beams.
