Definitions
- An optoelectronic component of the type described is known from B. Schneider, P. Rieve, M. Böhm, Image Sensors in TFA (Thin Film on ASIC) technology, ed. B. Jahne, H. Hauscker, P. G complicatler, Handbook of Computer Vision and Applications, pp. 237-270, Academic Press, San Diego, 1999).
- An optoelectronic component of this type consists of a matrix-organized or linear arrangement of pixels, so-called "pixels".
- the electronic circuits for operating the component ie the pixel electronics, peripheral electronics or system electronics, are usually implemented in CMOS-based silicon technology and form an application-specific integrated circuit (ASIC).
- CMOS Active Pixel Sensor Imagers MRS Symposium Proceedings, vol. 609, 2000
- a pin configuration based on amorphous silicon is used as the photodiode, i.e. a sequence of a p-conducting, an intrinsically conducting (intrinsic) and one n-type amorphous silicon layer.
- the n-layer usually forms the lowest layer facing the ASIC.
- the electrical contacts are formed on this side facing the ASIC, for example by a metal layer, while the contacting on the side facing the direction of light incidence in usually done by a transparent and conductive layer.
- further component structures are also possible, for example Schottky photodiodes, in which an intrinsic semiconductor layer is brought into contact with a suitable metal (for example chromium, platinum, palladium, silver), so that the metal-semiconductor transition forms a Schottky photodiode.
- Detector structures with controllable spectral sensitivity are also known (P. Rieve, M. Sommer, M. Wagner, K. Seibel, M.
- TFA image sensor can also be expanded by additional layers upstream in the direction of light incidence, for example by color filter layers (for example Bayer pattern, US Pat. No. 3,910,065).
- dark pixels there are so-called “dark pixels” in the arrangement, the dark signals resulting from these pixels serving as reference signals, which are subtracted from the actual image signals during operation of the sensor, for example, in order to increase the dark current adhering to the photodiodes and its temperature dependence eliminate. Furthermore, the dark signals are used in order to be able to compensate for differences in the amplifications of the column amplifiers as part of correction methods.
- the production-related realization of such dark pixels takes place by applying an opaque layer made of a suitable material to the photoactive layers of the optoelectronic component, which layer is structured in such a way that it areas to be darkened while it is removed over the photoactive areas.
- the diode is formed as a pin diode, then a negative potential applied to the connection electrode can be applied via the diode operated in the forward direction, taking into account a current-dependent one Voltage drop are transferred to the front electrode.
- the second exemplary embodiment of the second variant of the invention according to FIG. 4 differs from that as was shown in FIG. 3 in that an n-doped amorphous silicon layer 6 is additionally applied to the metal contacts 5.
- the diode formed in region P is designed as a pin diode, but otherwise the same structure results as in FIG. 3.
