Bandgap tuned vertical color imager cell |
摘要 |
A combination of materials is used to form the photodiodes of a vertical color imager cell. The materials used to form the photodiodes have different band gaps that allow the photon absorption rates of the photodiodes to be adjusted. By adjusting the photon absorption rates, the sensitivities of the photodiodes and thereby the characteristics of the imager can be adjusted.
