More Information
Summary:Image sensing devices are disclosed. In one example, an image sensing device includes a pixel unit cell with both event sensing (EVS) pixels and imaging pixels. The EVS and imaging pixels are configured to include event sensing and imaging pixel transistors formed in the same transistor layer of an integrated circuit assembly that also includes the photodiodes of the EVS and imaging pixels. The photodiodes are separated by a rear deep trench isolation (RDTI), and the EVS and imaging pixel transistors are arranged along (e.g., underneath) boundary areas formed by the RDTI, maximizing the space available for the photodiodes and economizing on wiring requirements for the EVS and imaging pixels.
