Tantalum Oxide Transition Mode Reactive Sputtering by Plasma Emission Monitor Control

Tantalum pentoxide thin film coatings are commonly used in optical applications, which require a high level of thickness uniformity and precision. Gaining better process control through a plasma emission monitor (PEM) can improve yield and deposition rates while supplying that high level of precision.

In this technical paper, you'll discover:

• How process conditions relate to deposition rates, optical film properties and thin film uniformity
• Deposition methods for tantalum pentoxide thin film coatings for optical applications
• The importance of using a PEM control system to vastly improve deposition rates
