Magnetron sputtering is a cutting-edge physical vapor deposition (PVD) technique widely used in industries such as glass manufacturing, electronics and solar energy. This technology enables the deposition of thin films with exceptional precision, uniformity and durability. From enhancing energy efficiency in buildings to improving the functionality of automotive glass, magnetron sputtering plays a pivotal role in modern manufacturing.

How it works

In magnetron sputtering, a plasma is confined near the target surface by a magnetic field. Ions from the plasma bombard the target, ejecting atoms that travel to the substrate and condense into a thin film. The magnetic confinement keeps electrons near the target, enabling efficient ionization at lower pressures and voltages.

Flexible process configuration

SEMIVAC sputtering systems can be constructed with various chamber and source configurations for depositing metals and dielectric thin films onto substrates. Key configuration options include:

• Power supplies: DC, RF and pulsed-DC to enable sequential or co-sputtering
• Geometry: adjustable magnetron-to-substrate distance to achieve desired uniformity and deposition rate
• Temperature & bias: substrate heating up to 800 °C with RF bias

Applications

The technology supports a wide range of applications, including:

• Optical coatings and ITO coatings
• Hard coatings and protective coatings
• Microelectronics patterning
• TCO in OLED applications

With ultra-high vacuum design and precise process control, magnetron sputtering remains one of the most versatile and reliable ways to produce advanced thin films — from the research lab to industrial production.
