Abstract:
1. A process for producing electrical contact connections for at least one component integrated in a substrate material having a first surface region and at least one terminal contact arranged at least partially in the first surface region for each component, the process comprising the steps of: applying an optically transparent covering to the first surface region; producing at least one contact passage in the substrate material, the at least one contact passage running transversely with respect to the first surface region; forming at least one contact location in a second surface region; thinning the substrate material starting from the second surface region substantially directly adjoining the at least one terminal contact; and producing at least one electrical contact connection from the at least one contact location to the at least one of the terminal contacts via the at least one contact passage, wherein before the at least one contact passage or the at least one contact location is produced, the optically transparent covering is applied.
