    摘要: A passive mechanism suppresses injection, into any active guard regions interposed between the edge of a photodiode array chip and the outer photodiode pixels or into the outer pixels themselves, of minority carrier current generated in the physically disrupted region at the edge of the semiconductor die created by cleaving, sawing or otherwise separating the chip from the remainder of the wafer on which the die was fabricated. A thin metallic layer covers all or part of the edge region, thereby creating a Schottky barrier. This barrier generates a depletion region in the adjacent semiconductor material. The depletion region inherently creates an energy band distribution which preferentially accelerates minority carriers generated or near the metal-semiconductor interface towards the metal, thereby suppressing collection of these carriers by any active regions of the guard structure or by the photodiode pixels.

    摘要: An improvement of the design of Schottky barrier infrared detector (SBIR) arrays, as taught by Roosild, et al. We describe modifications of the detector unit cell design which maximize the fraction of detector electrode area exhibiting full spectral emission response. In particular we recommend changes in the impurity density profile, or "doping", under the Schottky electrode. The new detector cell design can result in a two-fold increase in the photoemission of SBIR arrays, which have small detector cell dimensions.

    摘要: A sensor includes a first electrode and a second electrode, and a photo-active layer between the first electrode and the second electrode. The photo-active layer includes a light absorbing semiconductor configured to form a Schottky junction with the first electrode. The photo-active layer has a charge carrier trapping site configured to capture photo-generated charge carriers generated based on the light absorbing semiconductor absorbing incident light that enters at least the photo-active layer at a position adjacent to the first electrode. The sensor is configured to have an external quantum efficiency (EQE) that is adjusted based on a voltage bias being applied between the first electrode and the second electrode.

    摘要: Since a photosensor using a diode is incapable of perform refresh because of the structure, and the leak characteristics are unstable, the diode is not suitable for the photosensor. On the other hand, in a photosensor using a thin film transistor, since light quantity is very small, there has been a problem that feedback is difficult. A detection circuit converting an output current into a voltage is added to a photosensor using a thin film transistor. Thus, it is possible to convert a very small current into a voltage in a desired range enabling feedback. In addition, by varying resistors, capacitors, and the number of TFTs connected in the photosensor included in the circuit, it is made possible to change the sensitivity of the photosensor.

    摘要: A semiconductor device includes a semiconductor substrate having a surface; an active layer of a compound semiconductor disposed at the surface of the semiconductor substrate; and a Schottky barrier gate electrode including a multi-layer film alternately laminating a conductive refractory metal compound layer including a first refractory metal (M.sub.1) and a second refractory metal (M.sub.2) layer to three or more layers respectively, disposed on the active layer, thereby forming a Schottky junction with the active layer. The gate resistance of the Schottky barrier gate electrode can be held low and the internal stress can be reduced, whereby peeling off of the can be suppressed.
