| 发明名称 | Image sensor with reduced blooming | ||
| 摘要 | An image sensor for an electronic device. The image sensor includes a first light sensitive element for collecting charge and having a first saturation value and a well surrounding at least a portion of the first light sensitive element and having a first doping concentration. The image sensor further includes a bridge region defined in the well and in communication with the first light sensitive element and having a second doping concentration and a blooming node in communication with the bridge region and a voltage source. The second doping concentration is less than the first doping concentration and when light sensitive element collects sufficient charge to reach the first saturation value, additional charge received by the light sensitive element travels to the blooming node via the bridge region. | ||

| 主权项 | 1. An image sensor for an electronic device, comprising: a first light sensitive element for collecting charge and having a first saturation value; a well surrounding at least a portion of the first light sensitive element and having a first doping concentration; a bridge region defined in the well and in communication with the first light sensitive element and having a second doping concentration; and a blooming node in communication with the bridge region and a voltage source; wherein the second doping concentration is less than the first doping concentration; andwhen the first light sensitive element collects sufficient charge to reach the first saturation value, additional charge received by the first light sensitive element travels to the blooming node via the bridge region. | ||
