Abstract:
1. A method for making a microelectronic device comprising at least one electromechanical or electronic component provided with a suspended structure, the method comprising, in this order, the steps a), b), c), and d) of: a) forming on a supporting layer, at least one element bound to at least one anchoring block in at least one thin layer positioned on the supporting layer, said element being intended to form said suspended structure of the electromechanical or electronic component, b) removing a portion of the supporting layer at least under said element, so as to release the suspended structure, c) forming a passivation layer around said element so as to completely encompass said element, d) forming an encapsulation layer covering said passivation layer and said element, the encapsulation layer being based on a material capable of being selectively etched with regard to the material of the passivation layer, the passivation and encapsulation layers being formed so as to cover the thin layer, and the method further comprising after step d), steps of:
