YES vapor deposition systems provide total environmental control over the deposition process and accommodate a variety of functionally diverse silanes, for a variety of processes, on a variety of surfaces.

YES works collaboratively with Brigham Young University, Department of Chemistry and Biochemistry to develop and prove processes using the YES-ÉcoCoat. Read more about the collaboration here.

The YES-ÉcoCoat manual batch load, vapor phase deposition system is designed for today’s leading technology products that require precise surface modification over nanoscale surface areas. Whether it’s molecular specific bonding sites for DNA microarrays or to reduce stiction for MEMS devices, the capability to use a large number of different organosilanes provides the ability for precise surface modification. Flexibility of production is assured with an optional chemical delivery system that can handle up to 3 different chemicals and 3 different gases in a precise controlled operation.

Our manual load YES-ÉcoCoat Vapor Phase Deposition System is designed for versatile volume production with its configurable large capacity chamber. The flexibility of the chemical delivery system to use a wide range of organosilanes in small sample size bottles enables their efficient evaluation for precise surface modification research at low cost. Also, hydration of the surface can be controlled so that the vapor deposition coating provides a superior silane/substrate bond that is stable after exposure to atmospheric moisture, extending the time available between process steps. Incorporating a plasma cleaning function into the YES-ÉcoCoat enables the cleaning of the substrate prior to silane vapor deposition.

Reproducibility is crucial in the manufacture of products for the medical industry and the MEMS industry. Our tools are designed to control the process environment, so results are precisely reproducible, substrate to substrate and run to run.

Medical Industry Applications

  • DNA and oligonucleotide adhesion
    • APTES and similar aminosilanes provide molecular specific bonding sites for microarrays. The controlled process environment assures consistent deposition for the self-assembling monolayer films.
  • Glass slide surface modification
    • Methoxysilanes and ethoxysilanes offer a variety of functional groups to provide precise surface modification, resulting in improved sample adhesion. The quality of glass slides can vary in quality from batch to batch. The plasma clean properly prepares the substrate for consistent surface modification.
  • Antifouling coating for medical devices
    • Surface modification for biocompatible materials to minimize the buildup of proteins.

MEMS Applications

  • Wafer dehydration
      • The moisture on the surface of wafers will cause unintended reactions with various deposition steps. These reactions result in unstable surface which degrade over time. Vacuum dehydration provides a clean stable starting surface resulting in superior films.
    • Surface Tension Modification
      • As devices are made smaller and smaller, static friction (stiction) becomes more and more significant. By modifying the surface tension with a class of fluorinated organosilanes, the operating life of moving parts in MEMS devices can be significantly lengthened. A large variety of organosilanes can be used to produce a spectrum of hydrophobic surfaces which reduce stiction for MEMS devices.
      • Conversely, if surfaces need to be bonded together, other organosilanes can be coated which enhance bonding strengths between unlike materials.
