Protective Coatings


Atomic Layer Deposition (ALD) is widely used for thin protective coatings requiring high uniformity, conformality, and precise thickness control.


Key benefits include:

• Precision thickness control
Atomic-level control enables highly uniform and pinhole-minimized coatings.


• Conformal coating
Uniform coating of complex 3D structures and high aspect ratio geometries.


• Material versatility
Compatible with various materials including oxides, nitrides, and sulfides.

• Enhanced durability
Excellent thermal, chemical, and corrosion resistance.

• Barrier properties
Effective protection against moisture, oxidation, and aggressive process environments.


Typical applications:

• Corrosion protection
• Moisture barriers
• Semiconductor processing
• Optical and laser systems
• Functional surface protection
