.12 micron up to 150 microns, all developed by us. We provide both rolling shutter and global shutter pixels. The latter are used mainly in the industrial sensor and in the three-dimensional sensor markets. Our advanced technology used in CMOS image sensors enables improved performance such as low dark current, low noise, high well capacity, high quantum efficiency and high uniformity of pixels utilizing deep sub-micron process technologies, enabling us to offer very sophisticated and high-performance camera module solutions. Our state-of-the-art pixels are used in a variety of markets, such as the high-end machine vision cameras and the rapidly growing ToF 3D sensor market. In addition, our advanced global shutter technology and global shutter pixels, as small as 2.2um on BSI stacked wafer technology, enable excellent performance.
 
For the X-ray market, we offer our innovative patented “stitching” technology on 0.18-micron process as well as on 65nm technology on 300mm wafers and a variety of 15 to 150-micron pixels that are optimized for X-ray applications. These pixels are used by our customers in dental (intra and extraoral) and other medical X-ray products (such as C-Arm surgery machines, angiography and mammography) as well as in the industrial NDT (Not Destructive Testing) X-Ray market.
 
Our stitching technology, a cornerstone of our X-Ray sensors technology, enables semiconductor exposure tools to process single ultra-high-resolution CMOS image sensors containing tens of millions up to hundreds of millions of pixels at sensor sizes far larger than the photo exposure tool (scanner) field size.
 
This technology is used by us to offer large X-Ray sensors (up to one die per wafer) on 8” and 12” wafers as well as high-end large format photography and industrial sensors with special pixels that we have developed specifically for this market.
 
We have developed our next generation CMOS sensor technology, namely BSI and wafer stacking, which combines a digital CMOS wafer with an imager wafer that is then thinned for backside illumination (BSI) with billions of electrical Cu-Cu connections between the two wafers. We offer both BSI and stacking technologies in 200mm (in cooperation with a third-party that processes several steps of the BSI part of the process on our wafers, using our own developed BSI technology) and in 300mm in our own facilities at
