Substrate heaters are critical components in vacuum deposition systems, designed to ensure precise temperature control during thin-film growth. These heaters provide uniform thermal distribution, enhancing the adhesion, crystallinity, and quality of deposited materials. Whether used in physical vapor deposition (PVD), chemical vapor deposition (CVD), or advanced epitaxial growth, substrate heaters are tailored for high vacuum environments, supporting a wide range of temperatures and substrate materials. Built for reliability and efficiency, they are essential for applications in semiconductors, optics, and energy device fabrication.
