Abstract:
1. A method for manufacturing a housed circuitry integrated in a semiconductor substrate, wherein the integrated circuitry comprises an integrated circuit arranged in a circuit area of the semiconductor substrate and a stress-sensitive structure on the semiconductor substrate for detecting a mechanical stress component in the semiconductor substrate, wherein the stress-sensitive structure is implemented to provide an output signal, which depends on the mechanical stress component, in response to an excitation and to a mechanical stress component, wherein the stress-sensitive structure is arranged in a sensor area of the semiconductor substrate, wherein the circuit area and the sensor area are spatially separated from each other, wherein the method comprises the steps of: providing a non-housed integrated circuitry; determining the functioning of the non-housed integrated circuitry; housing the integrated circuitry in a housing; and determining the influence of housing the integrated circuitry in a housing on its functionality, wherein the step of determining comprises the sub-steps of:
