Abstract: The invention relates to a method for producing image sensors on the basis of TFA technology consisting including of an amorphous thin-layer system that has been applied on a crystalline ASIC. The inventive method enables the production of image sensors on the basis of TFA technology, which improve the picture quality at low luminous intensity by reducing the dark currents. The photodiodes in the thin-layer material that are configured as pixels are linked with transistor structures in the crystalline ASIC via back electrodes. The transistor structures have particularly low leakage currents due to implantation technology or optimization of the production process.

Abstract: To avoid the overexposure and underexposure of pixels which occurs with high image contrasts, each pixel contains a local autoadaptive control. With the help of this control, each pixel automatically ends its integration period as soon as it has integrated enough photoelectric current. An analog signal represents the length of the integration period selected by the pixel. Together with the integrated pixel signal, it represents brightness information with high dynamics and with low requirements regarding the dynamics of the individual signals. Because of their local adaptivity, the image sensors are suitable for all applications where high brightness contrasts must be processed, such as guiding a motor vehicle in highway traffic, nature films and astronomy.
