Method and fabricating electrostatic capacitance-type acceleration sensor and electrostatic capacitance-type acceleration sensor


In a method for fabricating an electrostatic capacitance-type acceleration sensor having a capacitor which electrostatic capacitance between a movable electrode and a fixed electrode changes according to the displacement of the movable electrode, the method includes: a step of forming a groove on at least one of the surface of an insulative substrate and the surface of a semiconductor substrate; a step of forming a hole in the semiconductor substrate so as to penetrate the semiconductor substrate at a position communicating with a passage formed by the groove; and a step of forming an electrode extraction hole in the insulative substrate so as to penetrate the insulative substrate, at a position communicating with the passage formed by the groove.. .
