摘要： In manufacturing a pressure sensor a recess that will form part of the sensor cavity is formed in a lower silicon substrate. An SOI-wafer having a monocrystalline silicon layer on top of a substrate is bonded to the lower silicon substrate closing the recess and forming the cavity. The supporting substrate of the SOI-wafer is then etched away, the portion of the monocrystalline layer located above the recess forming the sensor diaphragm. The oxide layer of the SOI-wafer here acts as an “ideal” etch stop in the case where the substrate wafer is removed by dry (plasma) or wet etching using e.g. KOH. This is due to high etch selectivity between silicon and oxide for some etch processes and it results in a diaphragm having a very accurately defined and uniform thickness. The cavity is evacuated by forming a opening to the cavity and then sealing the cavity by closing the opening using LPCVD. Sensor paths for sensing the deflection of the diaphragm are applied on the outer or inner surface of the diaphragm. The monocrystalline diphragm gives the sensor a good long-term stability. Also the sensor path can be made of monocrystalline material, this giving the sensor even better good long-term characteristics. An increased sensitivity can be obtained by making active portions of the sensor paths freely extending, unsupported by other material of the pressure sensor, by suitable etching procedures.

摘要： A micromechanical pressure relief valve arrangement comprises a stack of wafers. An active pressure relief valve is realized within the stack of wafers. A passive pressure relief valve is also realized within the stack of wafers, arranged in parallel to the active pressure relief valve. A check valve, also realized within the stack of wafers, is arranged in series with both the active pressure relief valve and the passive pressure relief valve.

摘要： A wafer assembly (30) includes a substrate (71), in turn including a wafer (70) or a stack of wafers. The wafer assembly (30) further includes an electrical connection (32) arranged through at least a part of the substrate (71). The electrical connection (32) is made by low-resistance silicon. The electrical connection (32) is positioned in a hole (84) penetrating at least a part of the substrate (71). A surface (78) of the substrate (71) confining the hole (84) is electrically insulating. The electrical connection (32) has at least one protrusion (75), which protrudes transversally to a main extension (83) of the hole (84) and the protrusion (75) protrudes outside a minimum hole diameter (85), as projected in the main extension (83) of the hole (84). Preferably, the protrusion (75) is supported by a support surface (81) of the substrate (71). A manufacturing method is also disclosed.
