    Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for an electromechanical structure capable of easily forming a mechanical reinforcing pillar with any width dimension in a sacrificial layer.
    SOLUTION: The manufacturing method for the electromechanical structure comprises a step of forming a well region 5
    1 which defines at least one mechanical reinforcing pillar in the sacrificial layer 2 by partially etching the sacrificial layer 2 formed on a single crystal material layer 1', a step of covering at least the free surface of the well region and its surrounding sacrificial layer with a first function-imparting layer 4 formed of a first material, a step of forming a filler layer 6 formed of a second material different from the first material on the first function-imparting layer 4 including the well region and then grinding the filler layer 6 to the surface of the first function-imparting layer 4 so that the filler layer 6 is remained only at the well region, and a step of releasing the electromechanical structure by at least partially etching and removing the sacrificial layer 2 through an opening 10 formed at the single crystal material layer 1'.

    Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of pressure sensor which tends to be compatible with standard CMOS processes or bipolar processes.
    SOLUTION: The pressure sensor is manufactured by jointing two wafers 1a, 1st wafer equipped with CMOS circuit 2, and 14, a 2nd wafer which is a SOI (Silicon-On-Insulator) wafer. The uppermost material layer of the 1st wafer 1a, a recess is formed. This recess is covered with a silicon layer 17 of the 2nd wafer 14, to form a cavity 18. A part of or whole substrate 15 of the 2nd wafer 14 is removed, to form a film from the silicon layer 17. Alternatively, the cavity may be formed inside the 2nd wafer 14. The 2nd wafer 14 is electrically connected to the circuit on the 1st wafer 1a. According to this design, use of standard CMOS processes for integrating circuit on the 1st wafer 1a becomes available.
