Classification: CPC G | IPC G

Claim 7:
8. A sensor device comprising:
a substrate;
an electrical insulation layer on the substrate;
an electrically conductive layer on the electrical insulation layer;
a first counter electrode patterned from the electrically conductive layer in an internal region in which there is a region that is electrically separated from the first counter electrode;
a first intermediate carrier that forms a movable electrode;
a spacing element:
that extends away from the first intermediate carrier towards the substrate so that the spacing element is located above the separated region;
that is spaced away from the separated region;
that has a lateral extension that is less than or equal to an extension of the separated region; and
by which the first intermediate carrier is arranged at a first distance above the first counter electrode;

an edge structure configured on the electrical insulation layer; and
a membrane that:
is anchored on the edge structure;
at least partly spans the internal region; and
encompasses in the internal region a region movable by a pressure;

wherein the first intermediate carrier extends in the movable region below the membrane, is electrically and mechanically connected to the membrane by contact points, and stiffens the membrane,
wherein the spacing element extends away from the first intermediate carrier towards the substrate in a region below the contact points.
