Low-reflective process for aluminum optimal for black materials in image sensors.
Image sensors that convert light into electrical signals and facilitate data transfer are utilized not only for imaging purposes in digital cameras and smartphones but also for distance measurement in ADAS (Advanced Driver Assistance Systems) and for sensing to ensure proper operation of industrial robots. The light-receiving part of the image sensor uses low-reflective black materials to prevent light scattering and eliminate stray light. Traditionally, when blackening aluminum materials, methods such as black chrome plating, black electroless nickel plating, and black dyeing of anodized aluminum have been employed; however, these methods have faced challenges related to environmental impact and difficulty in achieving corrosion resistance. In response, our company has newly developed a low-reflective process for aluminum, called the "Top Alcloy Process," which demonstrates a lower L value than conventional black anodizing and allows for direct application.
