具有耗尽调整层的彩色及红外图像传感器
摘要：
本申请案涉及一种具有耗尽调整层的彩色及红外图像传感器。一图像传感器像素包含形成于半导体层中的光电二极管区、钉扎层及耗尽调整层。所述光电二极管区从所述图像传感器像素的光入射侧接收可见光及红外光。所述钉扎层安置于所述半导体层的前表面与所述光电二极管区之间，而所述耗尽调整层安置于所述钉扎层与所述光电二极管区之间。所述耗尽调整层经配置以调整所述光电二极管区的耗尽区以减少由所述所接收红外光在所述光电二极管区中诱发的电荷载流子。
摘要（英）：

An image sensor pixel includes a photodiode region formed in a semiconductor layer, a pinning layer and a depletion adjustment layer. The photodiode region receives visible and infrared light from a light incident side of the image sensor pixel. The pinning layer is disposed between a front surface of the semiconductor layer and the photodiode region, while the depletion adjustment layer is disposed between the pinning layer and the photodiode region. The depletion adjustment layer is configured to adjust a depletion region of the photodiode region to reduce charge carriers induced in the photodiode region by the received infrared light.
