SK Hynix 2012 Sustainability Report has a part talking about its CIS business:
"SK hynix re-entered the CIS business in 2007 to diversify its product portfolio further and secure future growth engines. Its sales have been doubling every year since. The company provides customers in the mobile market with a wide lineup of products, ranging from 3M-Pixel and 5M-Pixel to 1M HD sensors. In order to keep up with rapidly increasing consumer demand for such high-end mobile products as smart phones and tablet PCs, it is accelerating its development of 1.1um, Back Side Illumination (BSI) sensors, and ultra-slim solutions. Its present goal is to begin mass production [of 1.1um BSI sensors? - ISW] in the second half of 2012. It also plans to diversify their applications to include high-value-added sensors, automobiles, and security devices."
