Semiconductor Sensor

A semiconductor sensor for determining at least one of physical properties and chemical properties of a medium, comprising:

• an electronic component with a sensitive surface, the electronic component being constructed on the basis of semiconductors with a large band gap, the sensitive surface, at least in regions with a functional layer sequence, having an ion-sensitive surface, the ion-sensitive surface being orientated away from the sensitive surface and is coated with at least one layer, the functional layer sequence being impermeable at least for at least one of (a) the medium and (b) one of materials and ions to be determined.

Use of a semiconductor sensor for detecting at least one of physical properties and chemical properties of a medium, the sensor comprising an electronic component with a sensitive surface, the electronic component being constructed on the basis of semiconductors with a large band gap, the sensitive surface, at least in regions with a functional layer sequence, having an ion-sensitive surface, the ion-sensitive surface being orientated away from the sensitive surface and is coated with at least one layer, the functional layer sequence being impermeable at least for at least one of (a) the medium and (b) one of materials and ions to be determined.
