摘要： The pixel for use in an image sensor comprises a low-doped semiconductor substrate (A). On the substrate (A), an arrangement of a plurality of floating areas, e.g., floating gates (FG2-FG6), is provided. Neighboring floating gates are electrically isolated from each other yet capacitively coupled to each other. By applying a voltage (V2−V1) to two contact areas (FG1, FG7), a lateral steplike electric field is generated. Photogenerated charge carriers move along the electric-field lines to the point of highest potential energy, where a floating diffusion (D) accumulate the photocharges. The charges accumulated in the various pixels are sequentially read out with a suitable circuit known from image-sensor literature, such as a source follower or a charge amplifier with row and column select mechanisms. The pixel of offers at the same time a large sensing area, a high photocharge-detection sensitivity and a high response speed, without any static current consumption.

摘要： A pixel is formed in a semiconductor substrate (S) with a plane surface for use in a photodetector. It comprises an active region for converting incident light (In) into charge carriers, photogates (PGL, PGM, PGR) for generating a lateral electric potential (Φ(x)) across the active region, and an integration gate (IG) for storing charge carriers generated in the active region and a dump site (Ddiff). The pixel further comprises separation-enhancing means (SL) for additionally enhancing charge separation in the active region and charge transport from the active region to the integration gate (IG). The separation-enhancing means (SL) are for instance a shield layer designed such that for a given lateral electric potential (Φ(x)), the incident light (In) does not impinge on the section from which the charge carriers would not be transported to the integration gate (IG).

摘要： The present invention discloses a photon detection device that is adapted to detect at least one packet of photons. The photon detection device may include a photon-sensitive element having an output, an amplifier; and a non-linear feedback (NLF) element. The photon-sensitive element generates charges upon the engagement of at least one photon packet therewith. An increase from a first number of charges in the photon-sensitive element to a second number of charges, results in a corresponding increase of a first reset time required to reset the first number of charges to a respective second reset time required to reset the second number of charges in the photon-sensitive element, whereby the reset time is non-linear to with respect to an increase in the charges. Additional and alternative embodiments are described and claimed.
