Samsung has used the so-called Copper technology, featuring a new pixel structure that enhances the fill factor over 55 percent and delivers high signal to noise ratio. Copper technology has been used for interconnects, and the resulting reduced pixel height gives high focusing efficiency and sensitivity. The overall performance is comparable to, or even exceeds, CCD quality, Samsung claims.
After announcing the 5M-pixel CIS last June, Samsung's 7.2M-pixel underscores the high potential and value CIS technology can deliver for future high resolution and quality imaging. Supporting the low power requirement in mobile or portable applications, the new CIS chip is claimed to perform at the same level and operates at a power level that is a mere 10 percent of its charge-coupled device (CCD) counterpart.
