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.
YES-ÉcoCoat is designed to achieve tight control over your process conditions:
Dehydration followed by silane vapor deposition coating provides a superior silane/substrate bond that is stable after exposure to atmospheric moisture, extending the time available between process steps. Chemical usage for a vapor deposition process is typically less than 1% of the amount needed for wet application processes, significantly reducing waste and chemical costs.
The vapor deposition process begins with vacuum chamber cycle purges to dehydrate the product. The chamber is evacuated to low pressure and refilled with pure nitrogen several times to completely remove water vapor. Nitrogen is preheated, which helps heat the product.
Once cycle purges are finished, the YES-ÉcoCoat pumps the chemical directly from the source bottle to the heated vaporization chamber without exposing the chemical to moisture.
YES-ÉcoCoat accommodates two chemical source bottles (option for 3) as well as wide variations of vapor pressures among different silanes. Processes are easily programmed using a touch screen operator interface.
