    Abstract: A micro or nano electromechanical transducer device formed on a semiconductor substrate comprises a movable structure which is arranged to be movable in response to actuation of an actuating structure. The movable structure comprises a mechanical structure having at least one mechanical layer having a first thermal response characteristic, at least one layer of the actuating structure having a second thermal response characteristic different to the first thermal response characteristic, and a thermal compensation structure having at least one thermal compensation layer. The thermal compensation layer is different to the at least one layer and is arranged to compensate a thermal effect produced by the mechanical layer and the at least one layer of the actuating structure such that the movement of the movable structure is substantially independent of variations in temperature.

    Abstract: An electromechanical transducer (1) has a pressurizing chamber (21) and a side-chamber (23) formed in a plate (11). On a driven film (13) forming the upper wall surface (21a) of the pressurizing chamber (21) and the side-chamber (23), a lower electrode (33), a driving member, and an upper electrode (35) are formed in this order. The driving member is composed of an operation section (31p) located over the pressurizing chamber (21), and an extended section (31a) extending from the operation section (31p) to over the side-chamber (23). The side-chamber (23) has a smaller width than the pressurizing chamber (21) in a second direction perpendicular to a first direction in which the side-chamber (23) is located beside the pressurizing chamber (21). The extended section (31a) of the driving member has a smaller width than the side-chamber (23) in the second direction.

    Abstract: Processes for making a membrane having a curved feature are disclosed. A profile-transferring substrate surface having a curved feature is created by vacuum bonding a membrane to a top surface of a substrate, where the top surface has a cavity formed therein. The surface of the membrane is exposed to a fluid pressure such that the membrane deforms and the undersurface of the membrane touches the bottom of the cavity. The curved feature formed in the deformed membrane can be made permanent by annealing the bonding areas between membrane and substrate. A uniform layer of material deposited over the exposed surface of the membrane will include a curved feature at the location where the membrane has bent into the cavity. After at least one layer of material has been uniformed deposited on the membrane, the cavity can be etched open from the bottom to remove the membrane from the underside.
