Abstract: A method of manufacturing a sensor device comprising: configuring a moulding support structure and a packaging mould so as to provide predetermined pathways to accommodate a moulding compound, the moulding support structure defining a first notional volume adjacent a second notional volume. An elongate sensor element and the moulding support structure are configured so that the moulding support structure fixedly carries the elongate sensor element and the elongate sensor element resides substantially in the first notional volume and extends towards the second notional volume, the elongate sensor element having an electrical contact electrically coupled to another electrical contact disposed within the second notional volume. The moulding support structure carrying (102) the elongate sensor element is disposed within the packaging mould (106). The moulding compound is then introduced (110) into the packaging mould during a predetermined period of time (112) so that the moulding compound fills the predetermined pathways, thereby filling the second notional volume and surrounding the elongate sensor element within the second notional volume without contacting the elongate sensor element.

Abstract: A controller configured for monitoring disturbances of a pressure sensor assembly includes at least two sensors. The at least two sensors are configured for measuring a pressure and wherein the at least two sensors have a sensor dependent measurement sensitivity for the pressure, and at least one of the sensors is sensitive for a disturbance with a sensor dependent disturbance sensitivity. A ratio of the measurement sensitivity and the disturbance sensitivity is different for the at least two sensors. The controller is configured for detecting the disturbance by comparing outputs of the at least two sensors.

Abstract: A piezo-resistor sensor includes a diffusion of a first conductivity type in a well of an opposite second type, contacts with islands in the diffusion, interconnects with the contacts, and a shield covers the diffusion between the contacts and extends over side walls of the diffusion between the contacts. Each interconnect covers the diffusion at the corresponding contact and extends over edges of the diffusion, and each island is at a side covered by its interconnect. A guard ring of the second type is around the diffusion. The shield covers the well between the diffusion and the ring and the edge of the ring facing the diffusion. If a gap between the shield and the interconnect is present, the ring bridges this gap, and/or the edges of the diffusion are completely covered by the combination of the shield and the interconnects.
