CVD (Chemical Vapor Deposition)
CVD (Chemical Vapor Deposition) is a common manufacturing process used to create high-quality coatings and materials. Think of it like spray-painting at a microscopic level, where special gases react to form a thin layer on surfaces. This process is crucial for making things like solar panels, computer chips, and protective coatings for tools. Companies use CVD because it creates very pure and uniform coatings that can make materials stronger, more resistant to wear, or give them special properties like being able to conduct electricity better.
