Abstract
An isolating arrangement for isolating a portion of a substrate from the remaining portions of the substrate, characterized by the arrangement comprising a pair of obliquely extending slots which merge with each other in the interior of the substrate to isolate a portion or region of the substrate from the remaining portion, except at least at one end of the portion extending between the slots. The slots are preferably formed by a laser-induced, wet-chemical etching and, subsequent to forming the slots, they can be filled with a material, such as metal or a ternary absorber material, to increase the isolation of the substrate region or portion.
