Abstract

The invention relates to an overvoltage protection device and to a method for fabricating such a device. A substrate (1) is provided with a first electrode layer (2), above which extends a second electrode layer (3) which is separated from the first electrode layer (2) by a distance (d) determined by the thickness of a spacing layer (4). The spacing layer (4) has an opening (5) which forms a cavity (6) between the electrode layers (2, 3).
