- Each of the microphotodiodes shown in Fig. 6A detects in a wavelength range different from those of the others, but the combination of the various microphotodiodes and the superposition of their sensitive spectrums covers the entire spectrum in which to detect. In this embodiment, the spectra do not overlap.
- FIG. 6C shows, by way of example, the sensitivity of the microphone phosphors over the wavelength in an exemplary embodiment, which differs from the preceding one in that the spectra at least partially overlap.
- FIG. 7 shows an exemplary embodiment of a wavelength-selective photodiode which can be printed by means of microtransfer printing as the semiconductor component 5 whose sensitive spectral range has been set by bandgap engineering.
- the semiconductor component 5 has a substrate 7 and a first contact 21 on its top side and a second contact 22 on its bottom side. These contacts 21, 22 may be n- or p-contacts.
- a detection area 8 with the active zone 11, in which the incident light 100 is detected.
- a wavelength-selective layer 25 is brought to.
- the detection area 8 is suitable for detecting radiation below a certain wavelength, designated by way of example by Y.
- An absorption layer 25 absorbs radiation below a certain wavelength, for example by X be characterized, so that this radiation no longer reaches the active zone 11. As a result, only radiation in the wavelength range between Y and X is absorbed in the active zone 11 since radiation above the range can not be detected and radiation below the range does not reach the detection area 8.
- FIG. 8 illustrates the above-described absorption behavior based on a representation of the absorption as a function of the wavelength.
- the detection area 8 of the wavelength range 101 below the wavelength Y is detectable, due to the shadowing of the radiation in the wavelength range 102 to the wavelength X only the Differenzbe range 103 between the wavelengths X and Y detected and absorbed.
- the sensitivity of a semiconductor component 5 and its sensitive spectral range can be selectively set.
- Figure 9 shows schematically another embodiment egg nes semiconductor device in the sectional view.
- the semiconductor device 1 has a plurality of Halbleiterkom components 5 on a component body 3, such as in Related to Figure 1 described on. To avoid repetition, only the differences from FIG. 1 will be described.
- this exemplary embodiment also has radiation-emitting semiconductor components 6 in order to form a sensor.
- the radiation-emitting semiconductor components 6 are printable components that have been applied by means of the above-described micro-transfer printing on the component body 3.
- the invention is not limited by the description based on the Ausrete tion examples. Rather, the invention comprises each of the new feature and any combination of features, which in particular any combination of features in the patent entitlements includes, even if this feature or this com bination itself is not explicitly stated in the claims or exemplary embodiments.
