We report on pixel-parallel three-dimensional (3D) integrated CMOS image sensors. Photodiodes (PDs), pulse generation circuits and 16-bit pulse counters are three-dimensionally integrated within every pixel by direct bonding of silicon on insulator (SOI) layers with embedded Au electrodes, which provides in-pixel pulse frequency modulation A/D converters. The developed sensor successfully confirms excellent linearity with a dynamic range of 96 dB, corresponding to a 16-bit value. Pixel-parallel video images with QVGA resolution (320 × 240 pixels) without pixel defects are obtained, demonstrating the feasibility of ultimate image sensors for the next-generation. |
