Abstract: The finding that with a reasonable effort a layer thickness and/or refractive index variation may be acquired which realizes different internal optical path lengths for impinging radiation whereby fluctuation of spectral sensitivity of the photodetector is reduced is used to provide image sensors with a less fluctuating spectral sensitivity with respect to different wavelengths, or photodetectors with a small fluctuation of the spectral sensitivity from photodetector to photodetector with respect to defined wavelengths, with a reasonable effort.

Abstract: A package including an electrical circuit may be produced in a more efficient manner when on a substrate including a plurality of electrical circuits the circuits are tested for their functionality and when the functional circuits are connected, by means of a frame enclosing the circuit on the surface of the substrate, to a second substrate whose surface area is smaller than that of the first substrate. The substrates are connected, by means of a second frame, which is adapted to the first frame and is located on the surface of the second substrate, such that the first and second frames lie one on top of the other. Subsequently, the functional packaged circuits may be singulated in a technologically simple manner.
