Abstract
A MEMS micromirror device includes a monolithic body of semiconductor material having a first main surface and a second main surface, with the monolithic body having an opening extending from the second main surface and including a suspended membrane of monocrystalline semiconductor material extending between the opening and the first main surface of the monolithic body. The suspended membrane includes a supporting frame and a mobile mass carried by the supporting frame and rotatable about an axis parallel to the first main surface, with the mobile mass having a width less than a width of the opening. A reflecting region extends over the mobile mass.
