Abstract:
1. An electrical component having a sensor and/or actuator chip, the electrical component comprising: a substrate on which a passivation layer and at least one structure that has at least one active surface area for the sensor and/or the actuator chip is located; an encapsulation that surrounds the chip and has at least one opening that forms an access to the at least one active surface area, and to the passivation layer, wherein, in the opening, the chip has an interaction surface that extends, at least partially over the passivation layer and the active surface area and wherein the operating position is in contact with a liquid or viscous medium; a first electrical insulation layer provided between the passivation layer and the substrate; a first conductor track layer that has at least one area that is configured as a conductor track provided between the passivation layer and the first insulation layer; a second electric insulation layer provided between the first insulation layer and the substrate; and a second conductor track layer having at least one area that is configured as a conductor track provided between the first insulation layer and the second insulation layer, wherein at least one of the conductor tracks is connected to the sensor and/or actuator chip, wherein said first conductor track layer is located completely outside of an area of the sensor and/or actuator chip that is covered by said opening, and wherein at least the areas of the first conductor track layer that carry an electrical potential are located completely outside of the area of the chip covered by the interaction surface.
