摘要
An image sensor pixel includes a first photodiode and a second photodiode disposed in a semiconductor material. The first photodiode has a first doped region, a first lightly doped region, and a first highly doped region. The second photodiode has a second full well capacity substantially equal to a first full well capacity of the first photodiode, and includes a second doped region, a second lightly doped region, and a second highly doped region. The image sensor pixel also includes a first microlens optically coupled to direct a first amount of image light to the first photodiode, and a second microlens optically coupled to direct a second amount of image light to the second photodiode. The first amount of image light is larger than the second amount of image light.
