DC sputtering is a physical vapor deposition technique used to create thin films on various substrates. The process involves bombarding a target material with ions from a plasma generated by applying direct current voltage. When ions strike the target surface, atoms are ejected and deposit onto a substrate positioned nearby, forming a thin film.

This method is widely utilized in the semiconductor industry for coating electronic components, manufacturing optical coatings, and creating decorative finishes. DC sputtering is particularly effective for conductive materials but has limitations when insulating materials are involved due to charge buildup on the target surface.

The technique offers advantages such as good adhesion, uniform film thickness, and the ability to deposit various materials including metals, alloys, and compounds. Process parameters like pressure, power, and distance between target and substrate can be adjusted to control film properties.

Despite its benefits, DC sputtering may produce fewer defects compared to other deposition methods and operates at relatively low temperatures, making it suitable for temperature-sensitive substrates. The technique continues to evolve with advancements in power supplies and vacuum technology, expanding its applications in modern manufacturing.
