The present invention provides an imager device with a floating diffusion region resistant to charge leakage. The floating diffusion region is formed having a first doped region and a second doped region which has a higher concentration of dopants than the first doped region. The floating diffusion region...http://www.google.de/patents/US7326607?utm_source=gb-gplus-sharePatent US7326607 - Imager floating diffusion region and process for forming same
