摘要： Optoelectronic component for converting electromagnetic radiation into an intensity-dependent photocurrent comprising a substrate formed in CMOS technology, in particular, with an integrated semiconductor structure (ASIC) and an optically active thin-film structure arranged upstream in the direction of light incidence and comprising in each case at least one layer made of doped and at least one layer made of undoped semiconductor material, which is connected to a microelectronic circuit arranged on the substrate by means of an insulating layer, within which are situated connecting means for contact-connecting the optically active thin-film structure to the semiconductor structure. The invention is based on the object of providing an optoelectronic component, and a method for fabricating it, which, on the one hand, can be fabricated more simply and, on the other hand, has a reduced dark current. This object is achieved according to the invention by virtue of the fact that the optically active thin-film structure has a layer sequence made of a metal and an intrinsically conducting amorphous or microcrystalline semiconductor material, in particular silicon and alloys thereof, which is applied directly to the planarized insulating layer.

摘要： The invention relates to an opto-electronic component for converting electromagnetic radiation into an intensity-dependent photocurrent, comprising a substrate (1) with a microelectronic circuit whose surface is provided with a first layer (7) which is electrically contacted thereto and made of amorphous silicon a-i:H or alloys thereof, and at least one other optically active layer (8) is disposed upstream from said first layer in the direction of incident light thereof (7). The invention also relates to the production thereof. The aim of the invention is to improve upon an opto-electronic component of the above-mentioned variety in order to obtain high spectral sensitivity within the visible light range and, correspondingly, significantly reduce sensitivity to radiation in the infrared range without incurring any additional construction costs. The invention is characterized in that a component is produced using a material in the intrinsic absorption layer (7) which is modified by an additional hydrocarbon content corresponding to alloy conditions, whereupon photons whose energy is less than the energy gap between two bands are absorbed only in reverse contact of the component which is sealed off from the substrate, as opposed to being absorbed in the first layer.

摘要： The invention relates to a method for producing a TFA image sensor in which a multi-layer arrangement comprising a photo diode matrix is arranged on an ASIC switching circuit provided with electronic circuits for operating the TFA image sensor, such as pixel electronics, peripheral electronics and system electronics, for the pixel-wise conversion of electromagnetic radiation into an intensity-dependent photocurrent, the pixels being connected to contacts of the underlying pixel electronics of the ASIC switching circuit. The method enables conventionally produced ASIC switching circuits to be used without impairing the topography of the photoactive sensor surface. The CMOS passivation layer in the photoactive region and then the upper CMOS metallization are removed and replaced by a metallic layer which is structured in the pixel raster, for the formation of back electrodes. The photo diode matrix is then applied and structured, said photo diode matrix being embodied as a pixel matrix, on which a passivating protective layer and/or a color filter layer having a passivating action can be applied.
