Color Filter and Micro Lens Array

CMOS Image Sensor (CIS) is an imaging device that performs the role of an electronic film in digital photography equipments. VisEra’s CIS products are used in a broad range of areas including digital cameras, camera phone, web-camera, notebook security devices, automobile, and miniature imaging devices used in medical applications. Image quality and competitive cost structure are keys to success in the image sensor market. To achieve high levels of image quality, our color filter and micro lens processes provide wide dynamic range and high sensibility. Current leading-edge devices use 1.4μm size pixels with ongoing development even smaller sizes such as 1.1μm and 0.9μm pixels. With an established manufacturing facility capable of running multi-chip technology modules at high volume and our mature supply chain, VisEra is able to offer highest levels of manufacturing flexibility and cost structure.
