    Abstract: The invention discloses a capacitive pressure sensor and a method of fabricating the same. The capacitive pressure sensor includes a fixed plate configured as a back plate, a movable plate configured as diaphragm for sensing pressure, wherein a cavity is formed between the fixed plate and the movable plate, an isolation layer between the fixed plate and the movable plate and electrical contacts thereof for minimizing the leakage current, plurality of damping holes for configuring the contour of the fixed plate as the deflected diaphragm when pressure is exerted, a vent hole extending to the cavity having resistive air path for providing equilibrium to the diaphragm and an extended back chamber for increasing the sensitivity of the capacitive pressure sensor. The capacitive pressure sensor is also configured for minimizing parasitic capacitance.

    Abstract: The invention relates to a method for producing a semiconductor structure comprising a buried cavity (64), wherein a first semiconductor substrate (10) having an upper face (22) is provided and a depression is formed in the upper face (22) of the first semiconductor substrate (10). In addition, a second semiconductor substrate (26) having crystal lattice planes and an upper face (28) is provided, said upper face extending substantially parallel to the crystal lattice planes, and one of the crystal lattice planes, which is located at a desired distance from the upper face (28) of the second semiconductor substrate (26), is weakened by means of ion implantation such as to generate a predetermined breaking plane. The upper face (28) of the second semiconductor substrate (26) is bonded to the upper face (22) of the first semiconductor substrate (10) under vacuum conditions, wherein the second semiconductor substrate (26) covers the depression (20) in the upper face (22) of the first semiconductor substrate (10) in order to form a buried cavity (60). The second semiconductor substrate (26) is split along the predetermined breaking plane, which leaves a membrane layer (34) of the upper face (22) of the first semiconductor substrate (10).
