Mo-coated glass substrate is a type of glass substrate that has been coated with a thin layer of molybdenum (Mo). Molybdenum is a transition metal that is widely used in the electronics industry due to its high melting point, high electrical and thermal conductivity, and low thermal expansion. In the case of Mo-coated glass substrates, the Mo coating is typically applied to the glass using a physical vapor deposition (PVD) process, such as evaporation or sputtering. The Mo coating serves as a barrier layer to prevent electrical and thermal degradation of the substrate over time, making Mo-coated glass substrates useful in high-temperature applications, such as high-power electronics, power modules, and more.
