Patent ID: 8821794

Claim:
A sensor chip for detecting particles, the sensor chip comprising a substrate; an electric connection structure arranged in a surface portion of the substrate and adapted for an electric connection to an electric connection element; a sensor active region arranged in another surface portion of the substrate and being sensitive to the presence of the particles to be detected; a continuous dielectric layer covering the substrate including covering the electric connection structure and the sensor active region, the sensor active region being configured and arranged with the dielectric layer to detect, via the dielectric layer, a characteristic of biological particles in a solution exposed to the dielectric layer, wherein the electric connection structure and the sensor active region are arranged on the same side of the substrate; a silicon carbide layer in contact with the substrate; a first silicon oxide layer in contact with the silicon carbide layer; a silicon nitride layer in contact with the first silicon oxide layer; and a second silicon oxide layer in contact with the silicon nitride layer and with the continuous dielectric layer.
