CMOS three-dimensional image sensor detectors with assured non collection of late arriving charge, more rapid collection of other charge, and with improved modulation contrast

摘要

A CMOS-implementable TOF detector promptly collects charge whose creation time can be precisely known, while rejecting collection of potentially late arriving charge whose creation time may not be precisely known. Charges created in upper regions of the detector structure are ensured to be rapidly collected, while charges created in the lower regions of the detector structure, potentially late arriving charges, are inhibiting from being collected.
