Claim:
1. A production method for a wafer equipped with transparent plates, comprising: formation of at least one row of through-holes in a wafer; formation of at least one strip-shaped recess in a wafer surface of the wafer, using a mechanical tool; wherein the formation of the at least one row of through-holes and the formation of the at least one strip-shaped recess are carried out in such a way that each of the through-holes of the same row intersects partly with the respectively associated strip-shaped recess, and an uninterrupted groove is formed in each intermediate region between two adjacent through-holes of the same row, the floor surface of the groove being oriented so as to be inclined relative to the wafer surface by an angle of inclination greater than 0° and less than 90°; and covering at least one through-hole with at least one transparent plate made of at least one material transparent to at least a sub-spectrum of electromagnetic radiation.
