Abstract
A production method for a wafer equipped with transparent plates includes: formation of a row of through-holes in a wafer; formation of at least one strip-shaped recess in a wafer surface, each of the through-holes of the same row intersecting partly with the respectively associated strip-shaped recess; an uninterrupted groove being 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.
