High n / Low n - Applications

Functional material with low refractive index for image sensor (IS) applications

High n / Low n material of Wave Control Mosaic™ is designed for mega-pixel CMOS and CCD color sensors of digital still cameras, camcorders, security monitors, and other special image sensing devices available in the market today.
The excellent design of high / low refractive index make the device highly sensitive.
High n / Low n material of Wave Control Mosaic™ is fully compatible with existing coater-developers at semiconductor manufacturing sites.

Concept

High n

This is an image of an application example using a high refractive material. In the arrangement of green, red, white (clear), and blue pixels, it prevents light entering through the clear pixels from mixing with the red pixels.

High n clear pixel

Low n

This is an image of an application example using low-refraction materials. It shows an anti-reflective coating that prevents light from being reflected in the green pixels, and a grid structure that prevents light from entering the red pixels from the green pixels.
