The OMEGAPIX2 chip embeds a matrix of channels implemented in two vertically integrated (3D) circuits and designed to read out 96×24 plannar pixels. form factor each pixel is 35×200 μm. first 3D devices's layer includes the analogue part channel processing, it will be bounded sensor by connecting inputs sensors pixels Through Silicon Vias (TSV); other performs digital memorization events manages sorting good after Level 1 (L1) trigger acquisition. In this paper, technology briefly described, some design considerations are discussed typical simulations shown. circuit has been submitted October 2011 waited received December 2012.
