发明名称 Depth sensing pixel, composite pixel image sensor and method of making the composite pixel image sensor
摘要 A method of making a composite pixel image sensor includes forming an image sensing array; and forming a depth sensing pixel. The depth sensing pixel includes a depth sensing photodiode; a first photo storage diode; and a first transistor configured to selectively couple the depth sensing photodiode to the first photo storage diode. The depth sensing pixel further includes a second photo storage diode different from the first photo storage device; and a second transistor configured to selectively couple the depth sensing photodiode to the second photo storage device. The depth sensing pixel further includes a first transfer gate configured to selectively couple the first photo storage diode to a first output node. The depth sensing pixel further includes a second transfer gate configured to selectively couple the second photo storage diode to a second output node. The method includes bonding the image sensing array to the depth sensing pixel.
