摘要： Methods, systems and apparatuses for an imager that improve the quality of a captured image. The imager includes a pixel having a photosensor that generates charge in response to receiving electromagnetic radiation and a storage region that stores the generated charge. A protection region assists in keeping undesirable charge from reaching the storage region.

摘要： An input signal comprising electronic carriers is injected into an impact ionization device with a high electric field whereupon the electronic carriers are accelerated toward an electron collector or hole sink and subsequently ionize additional electrons and holes that accelerated toward the electron collector and hole sink respectively. When properly biased an avalanche effect may occur that is proportional to the current injected into the impact ionization device via the input electrode. As a result, the input signal is amplified to provide an amplified signal. The described amplifier may be integrated with an input device such as a photodiode, and a transimpedance output amplifier onto a common substrate resulting in high performance high density sensor arrays and the like.

摘要： An anti-resonant reflecting optical waveguide structure for reducing optical crosstalk in an image sensor and method of forming the same. The method includes forming a trench within a plurality of material layers and over a photo-conversion device. The trench is vertically aligned with the photo-conversion device and is filled with materials of varying refractive indices to form an anti-resonant reflecting optical waveguide structure. The anti-resonant reflecting optical waveguide structure has a core and at least two cladding structures. The cladding structure in contact with the core has a refractive index that is higher than the refractive index of the core and the refractive index of the other cladding structure. The cladding structures act as Fabry-Perot cavities for light propagating in the transverse direction, such that light entering the anti-resonant reflecting optical waveguide structure remains confined to the core. This reduces the chance of photons impinging upon neighboring photo-conversion devices.
