The S5K4E5 is a ¼” optical format, 5 Mp image sensor designed for camera phones and camcorders. Samsung has indicated that it uses a lower-cost bulk silicon manufacturing process (which it estimated to be 4x to 5x lower wafer cost compared with SOI). The Imager Process Review is designed to take clients inside the process technology used to fabricate an image sensor, including analysis of the pixel and general logic in both planar and cross-sectional views. Preliminary reverse engineering findings of the S5K4E5 include: - Aluminum BEOL process - MIM column capacitors - Back light shield and bond pad metals - Through-silicon vias (TSV)
