Start with the news release Novel 3D IC technology brings new life to CMOS from BeSang , which we summarised at the time by saying "Breakthrough three-dimensional IC technology will enable low-cost memories and high-performance logic products with large embedded memory blocks.". Several months prior to that, we featured the news release Process puts more on CMOS image sensors from Tower Semiconductor: "Tower's advanced 200mm production line enables imaging characteristics previously not available in linear imagers and at a highly competitive price point.".
 
In May 2008, we covered the news from Mazet - take a look at Signal amplifier suits multichannel sensors which says: "The ability to convert photo currents to the single-digit nA range makes the MTI04C suitable for even the smallest sensor signals. ".
 
Take a look also at the news release from Timbercon, Electrical loopbacks speed XFP testing, as well as Sensor IC provides 15-year lifetime from Melexis, and Ambient light sensors promise easy application from Intersil.
