What are the main uses of Molecular vapor deposition (MVD) in protecting components?

Molecular vapor deposition (MVD) is a combined Atomic Layer Deposition (ALD) and Chemical Vapour Deposition (CVD) process that was developed to improve the protective performance properties of the individual ALD and CVD processes.

The MVD process provides protective thin films to many industries including:

  • MEMS (Microelectromechanical systems)
  • Semiconductors
  • Industrial Inkjet Heads
  • Display Technology
  • Advanced Packaging
  • Data Storage Industry
  • Biomedical
  • Genome Sequencing
  • µfluidics

How is the MVD coating process used in different industries?

The MVD process provides low temperature vapor deposition of coatings with many different properties in many sectors.

Consider the examples below where an MVD coating has been used to provide the appropriate film properties:

Surface Energy Control

  • Anti-stiction
  • Hydrophobic
  • Hydrophilic
  • Oleophobic
  • Oleophilic
  • Lubrication
  • Bio-functional layer

Device Protection / Package Sealing

  • Moisture barrier
  • Corrosion barrier
  • Chemical barrier
  • Gas/Oxygen barrier

Optical Films

  • Anti-reflection coatings

 Dielectric Films

  • Electrical insulation
  • Conformal films on high A/R

Adhesion

  • Adhesion promotion
  • Improved thermal stability
  • Improved mechanical durability

The MVD process offers great flexibility of processing thin films and it has now been considered for electronics protection.

About Dr Lee Hitchens

Dr Hitchens has been working in the electronics industry and the area of conformal coatings for over 25 years in various areas including sales and technical support. He has also been training people for almost the same amount of time in all areas of conformal coating whether that is materials & equipment selection, process development or troubleshooting to help them solve their particular problem. Recently, he decided that the industry needed a specific place where all of the useful knowledge on conformal coatings could be collated for users to find easily and use in their own production process. So, Nexus was born and he began the Nexus eBook project.
