he market for solid-state image sensors has been experiencing explosive growth in recent years due to the increasing demands of mobile imaging, digital still and video cameras, Internet-based video conferencing, surveillance, and biometrics. With over 230 million parts shipped in 2004 and an estimated annual growth rate of over 28% (InStat/MDR), image sensors have become a significant silicon technology driver. Charge-coupled devices (CCDs) have traditionally been the dominant image-sensor technology. Recent advances in the design of image sensors implemented in complementary metaloxide semiconductor (CMOS) technologies have led to their adoption in several high-volume products, such as the optical mouse, PC cameras, mobile phones, and high-end digital
