Abstract
An integrated circuit includes a photodetection region configured to receive incident photons. The photodetection region is configured to produce a plurality of charge carriers in response to the incident photons. The integrated circuit includes at least one charge carrier storage region. The integrated circuit also includes a charge carrier segregation structure configured to selectively direct charge carriers of the plurality of charge carriers directly into the at least one charge carrier storage region based upon times at which the charge carriers are produced.
Claims28
An integrated circuit, comprising:
- a photodetection region configured to receive incident photons, the photodetection region being configured to produce a plurality of charge carriers in response to the incident photons;
- at least one charge carrier storage region;
- and
- a charge carrier segregation structure configured to selectively direct charge carriers of the plurality of charge carriers into the at least one charge carrier storage region based upon times at which the charge carriers are produced, wherein the charge carrier segregation structure is configured to transfer the charge carriers into the at least one charge carrier storage region without capturing the charge carriers between the photodetection region and the at least one charge carrier storage region.

A photodetection method, comprising:
- (A) receiving incident photons at a photodetection region;
- and
- (B) selectively directing charge carriers of a plurality of charge carriers produced in response to the incident photons from the photodetection region into at least one charge carrier storage region based upon times at which the charge carriers are produced, wherein the charge carriers are transferred into the at least one charge carrier storage region without capturing the charge carriers between the photodetection region and the at least one charge carrier storage region.
An integrated circuit, comprising:
- a photodetection region configured to receive incident photons, the photodetection region being configured to produce a plurality of charge carriers in response to the incident photons;
- at least one charge carrier storage region;
- a charge carrier segregation structure configured to selectively direct charge carriers of the plurality of charge carriers into the at least one charge carrier storage region based upon times at which the charge carriers are produced;
- and
- a barrier below the photodetection region, the barrier being configured to inhibit unwanted charge carriers from entering the photodetection region.
