Abstract:
In a method for manufacturing a sensor chip a spacer (3) is arranged at the front side (11) of a substrate (1) at which front side (11) a sensing element (2) is arranged, too. Holes (14) are etched for building vias (15) extending through the substrate (1) between the front side (11) of the substrate (1) and its back side (12). After etching, the holes (14) are filled with conductive material to complete the vias (15). The spacer (3) provides protection to the sensing element (2) and the sensing chip throughout the manufacturing process.

Abstract:
The present sensing device comprises a sensor (1) for providing sensor data representative of a quantity to be measured. Together with the sensor (1) a radio frequency interface (2) for transmitting the sensor data is arranged in a casing (3). The casing (3) comprises an opening (33) for exposing a sensitive element (11) of the sensor (1) to an environment of the casing (3). A seal (4) is provided for sealing the opening (33) against an interior (3) of the casing (3). The sensing device can be used as autonomous humidity detector for detecting humidity e.g. in cars under test.
