    Abstract: A pressure sensor comprises a first substrate and a cap attached to the first substrate. The cap includes a processing circuit, a cavity and a deformable membrane separating the cavity and a port open to an outside of the pressure sensor. 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. The cap is attached to the first substrate 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. The first substrate comprises a support portion the cap is attached to, a contact portion for electrically connecting the pressure sensor to an external device, and one or more suspension elements for suspending the support portion from the contact portion.

    Abstract: A method for forming a micro-electro mechanical system (MEMS) device is provided. The method includes bonding a semiconductor substrate with a carrier substrate through a dielectric layer and patterning the semiconductor substrate into multiple elements. The method also includes partially removing the dielectric layer to release some of the elements such that the released elements become one (or more) first movable element and one (or more) second movable element. The method further includes bonding a cap substrate with the semiconductor substrate to form a first closed chamber containing the first movable element and a second closed chamber containing the second movable element. In addition, the method includes opening the second closed chamber and sealing the second closed chamber after vacuumizing the second closed chamber such that the second closed chamber has a reduced pressure smaller than that of the first closed chamber.

    Abstract: A MEMS capacitive transducer with increased robustness and resilience to acoustic shock. The transducer structure includes a flexible membrane supported between a first volume and a second volume, and at least one variable vent structure in communication with at least one of the first and second volumes. The variable vent structure includes at least one moveable portion which is moveable in response to a pressure differential across the moveable portion so as to vary the size of a flow path through the vent structure. The variable vent may be formed through the membrane and the moveable portion may be a part of the membrane, defined by one or more channels, that is deflectable away from the surface of the membrane. The variable vent is preferably closed in the normal range of pressure differentials but opens at high pressure differentials to provide more rapid equalisation of the air volumes above and below the membrane.
