Abstract:
An electromechanical device includes a stack consisting of an insulating layer inserted between two solid layers. The device also includes a micromechanical structure suspended above a recess and a nanometric structure suspended above the recess. The relevant position of the nanometric structure relative to the micrometric structure is defined by the delimitation of the contours of the two structures by etching a first surface of a substrate consisting of a solid layer so as to obtain trenches that define the structures.

Claim (Index 1):
A fabrication method of an electromechanical device comprising at least one micromechanical structure and at least one nanometric structure suspended above a cavity, the method comprising:\n the definition of the contours of the micromechanical structure and of the nanometric structure by etching a first surface of a first substrate, formed from a bulk layer, so as to obtain trenches defining the two structures; the formation of a temporary cavity disposed beneath the structure by isotropic etching of trenches defining the nanometric structure so as to form the nanometric structure; the sealing of the first surface of the first substrate with a second substrate; the formation of the cavity in the first substrate, by etching of a second surface of the first substrate; the closing of the cavity by sealing the second surface of the first substrate with a third substrate, the third substrate being formed from a bulk layer and an insulating layer in direct contact with the second surface of the first substrate; the elimination of the second substrate; and the etching of the first surface of the first substrate so as to open the cavity and form the micromechanical structure.
