What is a Thin Film?

A thin film is a substance 1 micrometer or less that provides additional functionality. Functionality of thin films can include electrical performance as a conductor or insulator, optical enhancement, or provide surface protection/modification. Thin films are crucial for modern day products and can be produced through different methods of vacuum coating. This post will specifically identify some of the benefits of roll-magnetron sputtering for thin film deposition.

What Are The Different Styles of Thin Film Deposition?

Thin films can be created in multiple different methods each has tradeoffs. Vacuum coating methods include physical vapor deposition (PVD), magnetron sputtering, thermal evaporation, chemical vapor deposition, and atomic layer deposition. Roll-to-roll sputtering provides significantly increased accuracy and unmatched uniformity compared to other solutions.

What is Magnetron Sputtering?

Magnetron sputtering is one of the most accurate methods of coating thin films. This method is great for highly precise applications such as demanding circuitry and medical devices. Through the sputtering process you can create extremely uniform layers with control that is unavailable from other deposition processes. This technique allows for many different substrates and materials for deposition.

Applications for Thin Films

Thin films are critical for most modern industries, including electronics and health care. Flexible conductors for batteries are made possible and could even be safer thanks to thin films. Within healthcare applications include biosensors that provide life saving readings of blood sugar where accuracy is critical to quickly provide effective care. The sky is the limit when it comes to creating innovative solutions with thin films.
