摘要： Some aspects relate to integrated devices for obtaining timing and/or spectral information from incident light. In some embodiments, a pixel may include one or more charge storage regions configured to receive charge carriers generated responsive to incident photons from a light source, with charge carriers stored in the charge storage region(s) indicative of spectral and timing information. In some embodiments, a pixel may include regions having different depths, each configured to generate charge carriers responsive to incident photons. In some embodiments, a pixel may include multiple charge storage regions having different depths, and one or more of the charge storage regions may be configured to receive the incident photons and generate charge carriers therein. In some embodiments, a pixel may include an optical sorting element configured to direct at least some incident photons to one charge storage region and other incident photons to another charge storage region.

摘要： Aspects of the present disclosure relate to techniques for reducing skew in an integrated device, such as a CMOS imaging device. In some aspects, multiple pixels of an integrated circuit may be configured to receive a same control signal and conduct charge carriers responsive to the control signal substantially at the same time. In some aspects, an integrated circuit may have modulated charge transfer channel voltage thresholds, such as by having different charge transfer channel lengths, and/or a doped portion configured to set a voltage threshold for charge transfer. In some aspects, an integrated circuit may have a via structure having a plurality of vias extending between continuous portions of at least two metal layers. In some aspects, an integrated circuit may include a row of pixels and a voltage source configured to provide a voltage to bias a semiconductor substrate of the integrated circuit along the row of pixels.
