Abstract
In accordance with an embodiment, a method for producing a moisture sensor includes providing a substrate arrangement, applying a sensor structure, applying a first cover layer on the sensor structure, locally removing the planar cover layer arrangement to expose portions of an insulation layer, applying a third cover layer on the exposed portions of the insulation layer, exposing the planar cover layer arrangement covering the sensor structure, and applying a moisture-absorbing layer element on the planar cover layer arrangement covering the sensor structure to obtain the moisture sensor.
