Wafer cleaning system NAMIKI-ECCLEAR - the world's first cleaning tool enabling high quality cleaning and drying for wafers less than 2 inches in diameter.
Until now, cleaning for new materials, such as small crystals or wafers less than 2 inches in diameter, has been limited to processes such as dip cleaning, resulting in unsatifactory cleanliness. Because of this, it has been a challenge to make devices that are able to utilize these new, advanced materials to their full potential.
NAMIKI-ECCLEAR has been built on Namiki's own cleaning know-how, developed through the manufacturing of sapphire wafers for LED applications, and features a newly-developed, original cleaning/drying mechanism for small-sized wafers. With these new functions, NAMIKI-ECCLEAR has a capability of high level cleaning and solves the previous issues of cleaning, which had become an obstacle in the development of these new, advanced materials.
Through NAMIKI-ECCLEAR, Namiki strongly supports the development of new advanced materials and manufacturing of related devices.
