    Abstract: The invention relates to an energy conversion device (10), comprising: - first (20) and second (30) electrodes intended to be connected to the terminals of an electrical load (60); - an electret (40) placed opposite the first electrode (20), mounted movably with respect to the first electrode (20) according to a degree of freedom in a plane, so that a relative movement between the electret and the first electrode induces a difference in potential between the electrodes. Moreover: - the electret (40) comprises a continuous layer exhibiting a series of projections (42) extending along a direction (z) perpendicular to said plane, the projections being distributed with a pitch (P) which is smaller than the travel between the first electrode and the electret; - the first electrode (20) exhibits faces (21) opposite the electret, these faces being distributed with an identical pitch to the pitch of the projections of the electret.

    SOLUTION: A protection film 20 composed of an SiO
    2 film is formed on a surface of an Si substrate 12, and its part is removed to form a sacrificial layer 23 made up of polycrystal Si on an opened etching window 22. A protection film 24 composed of SiO
    2 is formed on the surface of Si substrate 12 over the sacrificial layer 23, and an element film 13 composed of polycrystal Si is formed on it. An etching window 26 of the back side is opened on a protection film 21 of the back side. The Si substrate 12 is immersed in TMAH to etch crystal-isotropically the Si substrate 12 through the etching window 26 of the back side, and a through hole 14 is formed on the Si substrate 12. When the sacrificial layer 23 is exposed in the through hole 14, the sacrificial layer 23 is removed by etching, then a clearance 19 is produced between the protection film 24 and Si substrate 12, and the Si substrate 12 is etched crystal-isotropically from both sides of surface and back.
