Abstract
A pressure sensor comprises a first substrate containing a processing circuit integrated thereon and a cap attached to the first substrate. The cap includes a container, a holder, and one or more suspension elements for suspending the container from the holder. The container includes a cavity and a deformable membrane separating the cavity and a port open to an outside of the pressure sensor. The container is suspended from the holder such that the deformable membrane faces the first substrate and such that a gap is provided between the deformable membrane and the first substrate which gap contributes to the port. Sensing means are provided for converting a response of the deformable membrane to pressure at the port into a signal capable of being processed by the processing circuit.
