    Abstract: A pressure sensor device with a MEMS piezoresistive pressure sensing element attached to an in-circuit ceramic board comprises a monolithic ceramic circuit board formed by firing multiple layers of ceramic together. The bottom side of the circuit board has a cavity, which extends through layers of material from the ceramic circuit board is formed. A ceramic diaphragm, which is one of the layers, has a peripheral edge. The diaphragm's thickness enables the diaphragm bounded by the edge to deflect responsive to applied pressure. A MEMS piezoresistive pressure sensing element attached to the top side of the ceramic circuit board generates an output signal responsive to deflection of the ceramic diaphragm. A conduit carrying a pressurized fluid can be attached directly to the ceramic circuit board using a seal on the bottom of the ceramic circuit board, which surrounds the opening of the cavity through the bottom.

The capacitive pressure sensor of the present invention includes a substrate functioning as a lower electrode, a first insulating film disposed on the substrate, a hollow disposed in the first insulating film, an opening communicating with the hollow, a second insulating film disposed on the first insulating film to cover the hollow, a sealing film formed of a conductive material so that the hollow and the opening are partially buried through the opening, and an upper electrode disposed on the second insulating film to be superimposed with the hollow. According to the present invention, after the hollow is formed, the conductive sealing film is formed in the shape of an anchor at both sides of the hollow, and the upper electrode electrically separated from the sealing film and superimposed with the hollow is formed so that a hollow area which substantially affects the pressure detection process is limited to a certain area by the sealing film, and the parasitic capacitance acting as the noise in the non-hollow area during the pressure detection process is minimized so as to realize the micro-machined sensor.
