Rotary Magnetron

Rotary magnetrons are variants of a circular magnetron where the magnet set is mechanically rotated about a central axis. This embodiment, originally developed for semiconductor applications allows for the uniform coating of a stationary substrate with the smallest possible cathode diameter. Other applications of this technology include situations where material re-deposited on the target face generates defects in the growing film; in a rotary magnetron the entire target face is swept clean by a magnet set rotating between 20 and 600 RPM. Angstrom Sciences offer a range of rotary magnetrons, from 4" (100mm) up to 16" (406mm) in diameter, and are designed with an adjustable magnet configuration allowing for process optimization and uniformity enhancement. Our magnetrons can be mounted in internal or external configurations. Rotary Magnetron Benefits A rotary magnetron offers excellent uniformity without movement of the substrate. This combined with full face erosion.
