Custom Film Coating

Custom Film Coating

In many cases, chip wafers and similar components must also be equipped with dielectric layers. However, this is usually not part of the manufacturer's core business. Many companies do not have advanced equipment or proprietary technology to apply thin film coatings. Alfa Chemistry is a professional service provider in the semiconductor industry and has decades of experience in wafer film applications. Alfa Chemistry and its partners are experts in assisting researchers to meet their semiconductor thin film needs, and can coat substrates with specified diameters according to customer requirements, such as wafers required in microchip manufacturing and other industries. Small quantities are no problem. The customer delivers the cleaned wafers, indicates the required specifications, and will receive the finished coated parts in a few weeks. For more service information, please feel free to contact us.
