Denton Vacuum designs and manufactures systems to deposit ultra-thin metallic and dielectric coatings. These coatings are used in industrial and research applications ranging from optics, semiconductors, electro-optics, display, tribology, medical devices, to telecommunications. The ultra high purity required for the films that are in many cases just a few atoms thick, require that the deposition processes occur in a vacuum. Denton Vacuum is an organization based on and driven by process know-how. Denton's 130+ man-years of process engineering expertise in evaporation, sputtering and ion-assisted processes is the foundation on which the company has been built.

In general, the deposition technologies practiced by Denton Vacuum fall into four broad categories:

• Electron-Beam Evaporation per trillion
• Thermal Evaporation
• Sputtering, Ion Beam Sputtering
• Plasma Enhanced Chemical Vapor Deposition (PECVD)
